Anyway, the integrated grip isn't my thing anyway, and here I have to wonder if its a name game. If indeed the 70D is going upmarket, could that take over where the current 7D sits? Only then could a 1D level and spec body become more possible for a 7D successor. But still, I find calling that a 7D mk2 tough to swallow. I think that would deserve a new model number. 2D, 3D, 4D are still available, as are variations of the 1D name. I don't think it could be 8D or 9D since that would be positioned lower than 7D.
Assuming the rumoured announcement of the 70D is soon, the form the 70D takes will serve as guidance as to what may be offered in a 7D position, or 1D like position. My gut feeling is if the 70D leap-frog the 7D in spec and takes its place, then the integrated grip APS-C starts to make sense. If the 70D doesn't exceed the existing 7D, then I feel the 7D mk2 will be normal bodied.
I just can't imagine something called 7D mk2 being integrated grip, but it could exist as another name.
Easy. Three characters: 7-D-X.
