The 5DMKII has enough pixelcount, but for all else it is actually nothing more than an entry DSLR.
Feature wise the 5D MKII is a very 'old' camera in today's camera landscape except for its pixelcount as said.
Meaby after the 5D MKIII is released there is room for a small pixelcount full frame camera (which would then be the old 5D rebranded as 6D?) Although even that is not very likely to happen.....
or see my wishlist specs above
equip it with a full frame 7D sensor (18 MP)
and Digic V
better AF than 5Dii, but lesser than 7D
and voilà , here's your 6D
would be mine at least
