Canon to make a dual EF/RF Mount Hybrid Camera

Since Canon and Nikon are being pummeled by Sony in the Glass for mirrorless cameras, Canon has come up with a solution. They are making a mirrorless camera that has both the RF and the EF mounts ... somehow. I'm not sure how this works, but if they pull it off, they will just have added hundreds of Canon lenses(and 3rd party lenses) to be available to their mirrorless cameras. Nikon should take notice and do this with the F mount and Z mount in one Camera.
