Well, maybe one of these cameras include the 1D-C 4K camera ? Or has that already been accounted for ??
I would guess the mirrorless to be essentially the G1X with a lens mount. US$1100 (basic kit).
The 'entry-level' FF to be build in an up-sized T4i body, build quality and AF feature wise (including touch screen). But the ergonomics and size of the current 60D. Either rehashing the 5DII sensor or the 5DIII one with limitations on ISO up to perhaps 6400 or 12800. US$1500 (body)
The 7D replacement to be with 80% 1Div innards in the 5DmkIII body. Without an integrated grip. US$2200(body)
The high MP camera ? Doubt they would miss out on such a niche, probably 40+MP in a 5DmkIII body with 19pt AF, 4fps. ? US$4000 (body)
That would create enough of a gap in terms of price and product differentiation I believe
But my guess is only as good as everyone else's here.
