No, Gingerbread is going to be packing alot of what they talked about at I/O a couple months ago. Namely, all of the core apps, like the browser and music player, will be "detached" from the core OS like Google Maps Navigation and a number of other Google apps are now. This will allow Google to update these without relying on hardware manufacturers/carriers to push an OTA update and will go a LONG way towards ending version fragmentation. Also, they will be enabling the sending of intents to your phone from the web browser. The example they gave was creating a route in Google Maps on the computer then sending it to your phone with the click of a button.
Also, we may see music streaming over 3G or some kind of improved music store.
In short, Gingerbread will be a HUGE update.... I am just not sure if it will be 2.3, 2.5, 3.0, or something else.
