If they stay with the small sensor size, it makes more sense technically to shorten the registration distance. That 2mm increase in register distance was done for two reasons. One was to make it easier to put in a larger mirror for those very common super telephoto lenses, the other was to ensure that FD lenses were obsoleted. Note that Pentax managed the mirror issue quite well with the LX.
