Something like a 5Dmk1 but with a better LCD, live view, about 2 stops cleaner at high ISO (so 6400 can look like the 5Dc's 1600), AF points spread a bit wider, don't really need 19 or 45 or what not, although I suppose it wouldn't hurt. Weathersealing is a nice bonus, but not a must for me.
Don't care about more than 12 - 16 megapixels, high fps or any other gizmos they added since the 5D.
However, since there were some rumors about radio in new flashes, a radio flash commander compatible with the potential new flash system could be nice.
