By a wide margin the most used lens on my 1Dx is 24-70I can't see where IBIS is of that much use on 1DX. the camera is primarily used for sports with long glass that already has multi-mode IS and IBIS is beyond useless for panning shots. If the RS (or whatever it gets called uses the same pixel pitch as the 90D, it will be 83 MP and an awesome camera for portrait and wedding work. That camera will be used with standard and short tele primes with big apertures and it will need all the IS it can get, so I think that is the first place you will see IBIS.
