Canon uses the same flange distance as the Sony E-mount. Canon also uses the same mount diameter as the Sony E-mount.

So in theory they can do the exact same thing Sony has done going from Nex to A7 series.

 

Besides that, NEX APS-C lenses are worthless for FE mount anyway, so it would not matter of Sony would have made a new mount for FE, as they need FF lenses for it anyhow.

The issue is that they are obviously releasing APS-C lenses only at the moment. Thus even if the mount can do FF, they will struggle like Pentax in supporting FF out of the blue (albeit they certainly have substantially more capacity than Pentax).


I find it interesting that Sony pretty much abandoned APS-C. They have problably realised that Fuji/MFT were far ahead.
