The thing is, between 5D IV, C100 II, C300 II, C500 and respective successors I don't see why Canon would implement these things in the 5D IV. Looking at the focus of the cameras and their respective price points, Canon seems decidedly to go in direction of a clear segmented product portfolio with no cannibalisation. You probably won't get the C100 II features in the 5D IV, at least it would be a huge surprise, they clearly try to make the incentive for people to upgrade to the Cinema EOS line.
