I wonder if a significant sensor improvement is not possible. I don't follow Sony's sensor development very closely, except for this and Phase purposes, but it seems to me that a BSI 50mpx MF sensor is not out of the realm of possibility, though not perhaps likely. Just because it's not yet in Fuji's cameras does not mean one has not been developed or couldn't be available now or in the near future. That's like saying only Fuji can optimize Sony sensors, and no one can lap Fuji in a sensor marketing cycle. The 50S has been out a while now, and if the Fuji 50R was on a timetable that prevented it from waiting on a Sony BSI 50mpx sensor, then that need not necessarily mean Hasselblad would be unable to use it.
