Canon Working On A Full Frame Mirrorless Camera?

That's what a Patent spotted by Egami (translated) appears to suggest, if I am not misunderstanding the poor machine translation:

Canon SLR full size corresponds to 50 mm F1.2 and corresponds to the full size mirror-less 50 mm F2 of the patent is pending. Because large-diameter lens symmetrical with the axial chromatic aberration is corrected by using the anomalous dispersion glass which has been optimized, you can expect the performance. We are starting to design-conscious companies with full size mirror-less, the emergence of full-fledged full size mirror-less would be a matter of time.
