Hi Fred,
I am not the policy maker at Hasselblad so a little difficult to answer your first question.
The cost of the H series dropped dramatically at the last Photokina show, and I don't anticipate any reductions on that scale again.
Motion in MF is difficult due to sensor availability. CMOS is required for motion, and its not like the sensors Canon use are commercially available. Therefore we have to look to Kodak and Dalsa for their products. So it really depends on what those guys can produce in the future.
Otherwise, the H would make a nice motion platform. Great lenses, fluid manual focus, electronic aperture...
Best,
David
