Back on topic . . .
I'd like to see the C/Y mount revived for a DSLR. I'd also like to see one good film body, too, but I doubt that will happen. They could design a new autofocus line of C/Y lenses. And folks could still use their old MF lenses. After all, the only reason for the N-mount was to support full-frame sensors, and that market seems dead.
Perhaps a Zeiss Ikon R2C type camera with a longer rangefinder base is possible. Or an R3a in the classic mount!
Exciting developments. I hope something pans out.
