I think that it might be a different problem.  Digital backs are of real
use in the studio.  From what I know of them they use a lot of processing
power and a lot of electrical power.  Pentax produces what have been
acknowledged as field cameras.  Maybe film still rules in the field with MF.
Possibly 3rd party manufactures won't expend large amounts of capital creating
a product few would buy?
