Without having my hands on the new 1DXiii, it sure appears that if you were shooting live view with mechanical shutter at 20fps, there would be no lag or blackout issues. If that is the case, then is the only thing preventing Canon from making an R equivalent the new housing and battery to accommodate the RF lenses?
I can see if they want to milk the 1DXiii for a year or so first, as to not canibalize sales, but you have the sensor, mechanical shutter, and everything else you need to make a Sports R, that would probably be in the $4k-$5k range. Just need to make the weather sealed body, preferably with built in vertical grip and controls. Possibly they want to try new control layouts for the Rs and Rmkii before they go all in on a RDX.
I love shooting with the 28-70mm F/2, and really hope they will just plug the sensor and mirrorless part of the 1DXiii into a slightly more compact R body.
