A more modern, shrunk down 6D II makes a lot of sense(some hobbyists don't even care with micro-adjustment on their lenses, which won't be needed anymore), they will try to invite more people in the system with a cheaper body and a smaller, cheaper 24-70/4 kit lens. I guess it won't have the screen or the EVF quality of the EOS R (not great, but at least the battery drain should be lower) and it may skimp on 4k as well(but maybe with the new processor it will get it with the lesser IPB codec and without C-Log), but still capable as a stills camera.
