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
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...
