Frankly, I think you might want to keep up with film if only for the advantages of the Medium Format size and lenses. For the stuff you do now, maybe don't go for a 48-bit scan (seriously, anything over 16 bits is going to be major overkill), and scan the stuff you know is really good at the higher quality.

I just got myself a 6x7 camera, actually, because I wanted the advantages of the MF system and to start working with film seriously.
