Or the system might be derived from the 1DX MK2, but it would be a complete dumb-down version to not allow people to use 5D series for jobs intended for 1D series.
The problem with that is, look at the 5D3 AF vs the 1Dx (mark I). On paper, mostly iTR (though in reality there's more processing performance in the 1Dx).
Look at the 1Dx II vs the 1Dx I: on paper, same number of points, a better iTR system, and f/8 on all points.
The 7D2 and 5Ds already have iTR - indeed Canon's blurb for the 1Dx II mentions the iTR system "from the 7D2" (rather than the 1Dx I). The 80D has AF at f/8 on more than the centre point.
As such, what could they cut from a new 5D vs the 1Dx II, without making it look inferior to the 5D3, or existing not-a-1D bodies? It doesn't look as though they've given themselves much room to manoeuvre - which is surely good for potential 5Dx/4 buyers. Unless they throw us a massive curveball I guess.
