Simply, do not expect any sort of “niche” or “professional” mirrorless cameras prior to the release of more “entry level” products. A $4000+ camera simply doesn’t move anywhere near the volume that a sub $1500 camera would and at the end of the day, Canon needs more RF lens mount equipped cameras out there.  So yes, we expect to see a model under the EOS R before we see any sort of high megapixel or “professional” full frame mirrorless camera from Canon.
