New Unreleased Canon Gear Has Appeared for Certification

I don't believe the M mount would have an adequate image circle to cover full frame. I could be wrong.

It does. It's almost identical to the Sony E/FE mount size.

It is perfectly possible to make a full frame image circle with a back focus of 18mm. The lenses would need to be a concentric design as much as possible and the lens image circle preferably larger than the current EF system. The optimum flange distance is currently believed to be between 17 - 22mm. An industry group made up of people from Sigma, Sony, Zeiss, Leica, Fuji, Cooke, Angenieux, Panavision & Arri (but not including Olympus, Canon, Nikon & Panasonic) have already discussed the merits of such a standardised approach although I doubt a single common depth will be adopted.

Sony have proved its possible.

I’m disappointed in the dynamic range of PC2328, whatever it is.
