I am not trying to get into a flame war with those inclined to Canon it's just you can buy a Sony A77 Mark 2 for $1100 rather than $1800. OK there are those that insist that they need a certain lens that only Canon can provide, but I can't but feel that you are (again) for a ride financially.
It's not "lenses that only Canon can provide," it's a gazillion dollars in lenses, speedlighting systems, and multiple bodies
that I already own. Worse, for me, it's what my employer already owns -- getting a new camera through the budget cycle is relatively simple, but buying an entirely new system from scratch would be asking a bit much.
I'll be interested to handle the 7D Mark II and see some images from it. My 1D Mark IV bodies are getting kind of old, with a lot of shutter cycles. My new 5D mark III is terrific, and if the new 7D is close to an APS-C version of that camera, I think they would complement each other well. I am no longer shooting sports or news full time, so I don't really need the 1Dx, but the speed and AF is useful when I do get that sort of assignment, and I can get a pair of 7D Mark II for about half what a single 1Dx will cost.
