Right now everything between the 650D and the 5Dmkiii is just a bit tired and old. Whatever it does (7Dmkii, 70D, 6D...whatever) Canon needs to do something quickly because right now it just seems to be floundering.
Very true however I think for your particular situation is that its unfortunate for you that the segment of the line where you are most interested in are in the trough of the wave cycle.
what strikes me as strange is how the 5Dmk3 and 650D released very close to each other so there must have been alot of concurrency in the design have ended up with new features in the 650D that are not in the 5Dmk3, or 1Dx.
Would AF in video in the 5Dmk3 made video people happier? perhaps some
quite likely it would have drawn more fire. touchscreen? personally i'm glad the 5Dmk3 didnt get one
but i'm sure many people would like it.
When looking at some of this stuff it makes the planning/ roadmap/ product range design seem quite hap hazard
so while I can see your frustration I guess you can console yourself that whatever gets announced in your area of interest it most likely will inherit some features that much higher end bodies dont have
this happened with the 7D too it got heaps of goodies that the 1D and 5D lines missed out on
