Not posting about my perception as much as a general consensus here that the 8gb is for apps and it will release end of the month.
My own perception (not worth much, of course)
1. 8gb built in for media storage - not part of framework for app installs.
2. Same display as Nexus (hope I am wrong)
3. Capped at 768mhz (Verizon did it to the Droid, which has a more efficient chipset- why not the Snap that is more power hungry?)
4. Preorder end of month and will ship in early May
5. Device will be HUGE for Verizon sales, but Droid will still see steady sales due to having a keyboard.
6. (added) I think the manual is wrong and the card is accessed by removing the battery.
All conjecture, but based on the most logical mean of all of the current information I have read

As far as the camera being 5 or 8mp, I could care less, since the speed of the image capture is more important to me (as should be for everyone).
Added:
Biggest stretch is the 768mhz thingy- hope you all are correct and not capped. It was dumb for Verizon capping the Droid, so ditto for the Incredible (if is capped).
