You have to remember something when using the Hero/Eris as basis of comparison. The jump from 1.5->2.1 was very very big in the terms of the underlying OS components. So HTC was putting a lot of effort into making Sense work properly for 2.1. That's where the delay came in, not in the manufacture being lazy.
how much better is dual core?

The wait for 2.2 on my Dinc seemed to take forever, but when you keep in mind that the only devices that got 2.2 before the Dinc are the Evo, Moto Droid, Droid 2 (which launched with Froyo, no update necessary) and N1 (duh), HTC and Verizon look pretty good, especially when HTC has Sense to contend with (and notice that no Motoblur phones updated beforehand). Some other high end phones, like the Droid X, took longer to get the update, and the Galaxy S phones are still waiting for it. Also, a friend of mine with a US Cellular Desire (which I believe has been updated on many European carriers) has yet to get the update, so smaller carriers don't seem to do too well with this.

It may have been a big jump, but HTC had the 2.1 source code before VZW had the Eris for sale because they were working on the N1 before that and the DInc shipped with Eclair. From my memory HTC handed over the build to VZW a long time prior to the OTA but we had to wait for the then current "Flagship Phone" ie: OGD to get it first then along comes the Eris replacement ie: DInc had to wait on that hype to pass then the eris got it. So while the survey shows VZW pushes out OTA's the fastest doesnt mean every phone does.
Honestly... Android, in its current state, is not optimized for dual-cores.
Honeycomb is starting to head down the right path by using code that is optimized for dual-core architecture... but who knows how long it will be until dual core support is included for every day users.
Some devs may attempt optimizing their current ROMs for dual-core... but this cannot be an easy task.
For now, I would not worry about all of the marketing hoopla about a dual-core smartphone. (now tablets are another story if Honeycomb lives up to expectations).
I am going to look for the device that fits my needs and will be suitable for me. I am not concerned about dual vs single core at this time since you will not be able to fully take advantage of the dual core CPU anyhow.

A dual core processor may also help with redering the screens on a higher res device. Sure, it's only a few hundred pixels, but the Bionic may benefit from the extra processing power in that case...especially from a graphics point of view.
bmcclure already answered this as have others a dual core device is virtually useless at this point in time until honey comb drops that extra core is a dead weight.
So a Tegra2 processor that specializes in graphics power gives you NO help? I find that hard to believe...regardless of the underlying OS code. Fine, it's not optimized, but that doesn't mean it's not helpful at all.
The dual-core CPU has nothing to do with the GPU (AFAIK). This may be different in the mobile SoC realm, but the GPU is on the same die as the CPU in most cases (for mobile CPUs) but that does not mean it will benefit from added graphics processing.
Dont believe me, don't matta to me
but take a stroll around the thunderbolt forms and read more on the facts then come back and appologise
The current benefit of a dual-core CPU would probably be that the underlying architecture is more efficient. Even though the OS cannot optimally take advantage of both cores, the CPU should run efficiently. The power savings on Gingerbread will not be nearly as good as they should be on Honeycomb. (notice, I say "should" since none of us have used Honeycomb to know if dual-core lives up to all the hype -- I assume it does, but there are no real-world tests).
Anyhow. The Tegra2 you mentioned is simply a dual Core Coretex-A9 CPU paired with the nVidia GeForce mobile GPU. The SoC is a great architecture for mobile devices.
Dont believe me, don't matta to me
I'm pretty sure I'll just wait till they come out for YOU to be proven wrong. It's just a fact of computer architecture. The differences may not be mindblowing (whatever you consider that to be), but there will be differences. And we should probably wait till these things are actually in the wild to make any assumptions either way really. It's all hypothesis right now.
One thing I do know...my Fascinate seems to be faster than my X, especially with regards to gaming...is that because of the dedicated graphics chip? Yes. A Tegra2 with the dual core CPU and GPU is gonna be even faster. But we'll see how much faster when it's actually released.
Until then, we can all stick to guessing.
I honestly do not get your point. The Fascinate is clearly be better than the OMAP CPU in your Droid X... so who was comparing?!
And the new Qualcomm Snapdragon in the TB will also be a highly efficient architecture (not even close to the same as the Nexus, EVO, etc). I agree that the comparisons should wait until both devices are available to test, but this thread specifically asked how much better dual-core CPUs would be! For the current state of Android OS, they are not worth the hype and hoopla. Android is not optimized to use them. It would be like running Windows 98 on a dual-core CPU and saying it is faster.
You never know, the dual-core CPUs could also be major battery hogs until optimizations occur as well. If both CPUs are running they could either drain the battery, or they could work efficiently and properly... resulting in similar battery performance as a single-core. Some say that dual-cores could even help with battery usage since each core would be spending less time processing and more time idle.

Hot topic lol. Simple, duel core runs less volts and more processes. Nvidia didn't start yesterday. You can bet it is better in every aspect. Sgs has a omap with the SAME architecture as the omap in the X. The gpu is better in the sgs, but the ram is hard partitioned, so there goes that.
It is like a sales guy yelling at you to buy the last single core units to make room for duel core advantages. He will tell you that you are missing nothing, then when the duel core devices drop, only then do you realize the sales guy was wrong and science is actually real.

And that is only because of the GPU because its the same architecture/same speed, So it seems to me your just makin an assumption as to its possible that both cores will work that we may have it wrong ... case in point Viewsonic tablet Dual cores very fast still only uses one core and same battery consumption as one core. Now you will be right once 3.0 honeycomb drops, so if your gonna outright call me wrong do your homework and get your facts straight because people who dont know read this stuff and your misinformation misleads people to believe that they must wait for dual core, when in reality
a newer generation single core will be extremely fast an plenty capable with the new graphics processor to run plenty of games extremely well. And if you so choose to throw in the special Tegra 2 based games then you must think everyone must drop what phone they have and by a brand new dual core but not optimised phone just so they can game on them? Get real!
Sorry to drag up a 2-week old thread, but I saw a pretty cool article on ARM processors that was kinda relevant.
Very interesting read: Anand discussed in details that Android 2.2 can & does indeed benefit from dual core phones.

Dual cores are worthless unless you are into gaming, which really there isnt that many good games you can use on a phone with no way to control them other then the touchscreen. So other then that, dual core is worthless. If you want to game, buy a DS or PSP or play at home the old fashioned way on a wii, xbox 360 or ps3.
To be honest, dual core wont make angry birds any better.

Also, plenty of people out there that would LOVE to have an all in 1 device so they aren't carrying a phone & a portable gaming unit. Do you realize how HUGE the mobile smartphone gaming sector is going to get in just the next 5 years ?
Can we stop going over and over this question?
We have said there is really no use to dual core till the software supports the hardware. Thats not going to happen till Honeycomb, and there is no info on if and when that will hit phones. I have said before and I will again we are a ways off from seeing dual core phones that actually use both cores well and efficiently.

You're probably right about mobile gaming becoming huge in the upcoming years no argument there. However, in my opinion people who use portable gaming devices and want that ability on their smart phone are the minority when compared to all cell phone users.
Let's use me as an example. I mean, I'm 28, I have a job and most of my friends have careers and some are married and even have kids now. All of them have smart-phones, whether it is an Iphone, android, and blackberries. What's their primary use for their phones? Text, calls, email, web. Probably in that exact order to. As far as games go, they play Words with friends, Angry birds, and other puzzle like games. They don't even care for graphic intensive games at all.
Who do I see playing PSP's and DS's? Young kids and/or gamers if they are older. And young kids/teens usually can't afford smartphones unless mommy buys it. I guess what I'm trying to get at is that even though phones will eventually all be dual cores, most users will not be using the phone in a way to take advantage of its full potential. Most users in my opinion will keep using smart-phones for email, text, web surfing, with intensive gaming a close last.
