This is like a holy war that rages on in this forum from time to time.
Medium format survivalists vs. the great hordes of professionals that might, have, will, will not buy a new medium format back.
It doesn't matter except to the people that want to use a digital back, or the people that sell medium format backs.
Everybody else is just an innocent bystander because nobody from Phase or Hasselblad is going to tell your their sale figures, or future plans..
I own two medium format backs, they work fine, but all I know is my work has changed and changed quickly and until I find a medium format back that can shoot this with LED's or medium powered HMI's then I can't continue to invest in that format unless things change.

I sincerely wish them all well, because they make professional equipment and competition should move their products forward.
Still, there is no denying that the future is in stills, motion and a combination of the two. In fact I find it fascinating that both Phase, Leaf and Hasselblad us motion imagery on their websites to sell their still cameras.
I think that tells you something.
IMO
