Not the 7D Mark III but let's call it a Mark "II+" with two minor but noticeable and doable improvements Canon could make in the very near future, talking early 2017, features which should've been there in the first place.
1) a touchscreen! -- Once you've used one, it's hard to go back. Dual pixel AF deserves a touchscreen; also for pinch to zoom, swipe to review, to navigate menus. The 70D/80D and most recent Rebels have one, even the SL1/100D has a fixed touchscreen, why not the top-end 7D2?
2) built-in wi-fi -- Sure there's a quite cheap adapter available but it has meant giving up the SD slot and thus the dual card feature, so just put it in there.
Make this hypothetical 7D2+ available while they do R&D on wish list specs like a new sensor, maybe a faster drive that goes up to 12 fps, putting 4K in there, and all that for a full-blown Mark III. If Canon are planning a 7D3 release earlier than expected, then great. But, going by release cycles, as the 7D2 was released fairly recently (by Canon standards) in late 2014, with the original 7D in 2009, a Mark III could come as late as 2019, or at least late 2018. So in the meantime, just those two changes would make a 7D2+ a bit more future-proofed.
