Its called vaporwear. The way HTC plays the game is they announce all kinds of accessories and then wait to see how well the phone sells. If it hits a certain number they make the accessories, if it doesn't then they don't. The EVO will never sell well because its only on Sprint and because HTC can't get the screens to make them and by the time they do the EPIC will be taking all of the EVO sales.
If you don't believe me then look at the Nexus1. HTC announced a dock for it as well but then never produced it because the phone did not sell well enough due to Google's stupid web store strategy.
Your wrong.... I ordered and used a Nexus One for 3 months... I had both the car dock and the desktop dock and they were both only available at the Google phone store. The Nexus one car dock was kind of neat as it had a special opening on the back so you could actually make video and pictures from your phone docked to the windshield.
The thing was the Nexus One came out in January and if I am not mistaken the desktop dock came out in or around March and the Car Kit came out in late April or early May....
I think they rushed the phone to market to get it ahead of the iPhone but even that makes little sense in secondary accessory/kits since they announced the phone back in March and then had their big party in May and released the phone in June.... Heck even two weeks before launch Google gave out a rumored 5,000 at their conference so people had to have their hands on them.
Also the EVO does not even use a Samsung Display so how or why would Samsung be screwing HTC on displays? Doesn't the EVO have a Epson or Novatec display? Does Samsung make these two displays?
Even Seidio has their car kit and desk top dock listed as "Under Development" when I asked them back in June they told me July/August on the car kit.
I did pick up the universal mount from Sprint and I just didn't like it... I want one made just for the phone...
EVO sales numbers are solid... The Epic won't steal any thunder from the EVO... The Epic will be for those who want a slide out keyboard.... Most of the people who buy the Epic are going to want the physical keyboard. and all this "Because it's only on Sprint?" is B.S. AT&T is FAMOUS for a crappy network and Apple still sells million's of iPhone's... The EVO is Sprints first real market changing phone. I left Sprint for AT&T and the iPhone and couldn't wait to come back.... I would have easily paid the ETF on the iPhone but Sprint never had a phone that I felt was worth it.... The EVO was finally it... Besides Sprints 3G network is actually bigger than AT&T's and second only to Verizon....
