Here's my "top secret" leaked spec list.
The 5DII replacment body will be:
Black or black-ish
Take still pictures, and probably video
Will most likely not use film
If digital, I have it on good authority the sensor will be larger than m4/3, but smaller than 645
Feature Auto-Focus
Will probably be EF mount
Will almost certainly be branded as Canon
Might have some type of removable flash memory based medium for picture storage
Will prominently feature button(s) <-note the plural, for key functions like taking a picture or changing setting
You heard it here first folks... :
