Just my two cents worth. I think the DSLR basically is dead as far as the future of cameras go. Now if for some mythical reason Canon was not able to adapt their EF line of lenses to the R bodies then I would agree that the future would hold a 5DV for it would take some time to rebuild the RF lens line-up. Canon has always been about the glass not the bodies. So with this scenario being erased a 5DV doesn't make much sense. The elephant in the room between mirrorless and DSLR's is EVF refresh rates, shutter speed and for some buffering capacity for tracking fast action photography. The 5D series was never developed with this in mind to begin with so it would not fulfill any of the current limitations that a DSLR has over a mirrorless. There is a big difference between personal preference and performance. The EOS R was basically a mirrorless 5DIV replacement, thou admittedly in a less than stellar configuration for some, (me included). I'm sure when the automobile first appeared many folks saw no reason to replace the horse and buggy. These machines where too expensive, complicated and you now had to take your transportation somewhere else to fuel it instead of be able to feed it yourself. Guess who won.
