I cannot see the camera being almost better than a 5Dmark3 and with these specs it seems it is, it wouldn't make sense for canon, also the big firmware is a big indication that it isn't going to move for a while, I would assume a 7D2 upgrade is a 6D
Given that the 7DII will be APS-C, Canon can allow it to be better than the 5DIII in many areas because it won't make it a better camera than the 5DIII, just different. The 7D has its own identity as a great camera for sports, action, birding, etc., such that many owners of full-frame bodies also have a 7D. The specs of the 7DII need to be equally clearly differentiated so that 5DIII owners will want one. To me, the rumoured specs seem entirely reasonable.
