afaik phase is still selling more backs then anyone else....of course a good amount has been as H mounts....somehow i cannot imagine that this has hit phase completely by surprise....a "secret" collaboration with rollei/F&H would be the best "revenge.....i just don't see everybody who has made a desicion to buy a phase back will now just say: "well, i guess it is the H3D for me then"....especially if they were just screwed by hasselblad after just buying a H2 (and a P45 or whatever)....
unless mamiya comes out with a completely new camera, (could be the same mount, to keep it in line ith 645afd and RZ), i don't see that phase would go exclusive with mamiya....the lens/shutter/sync issue still remains....
Hy6 is the only logical solution...and as the biggest player in the back market, i can't see why rollei/F&H would NOT want phase with them.....leaf and sinar can sell a lot of bodies, but with phase n board, those sales would double or triple, especially after the H announcement.....and this system has it all....latest technology, to a certain extent even proven technology (it is a step up from the 6008AF), the best lenses in the market with the widest range of lenses (compared to any system) and the biggest system (X-Act,....).....also to consider: rollei/F&H will make more money on selling the rollei Hy6....i am sure sinar and leaf get their bodies (more or less) for free in order to sell lenses....
anyone who bought a back made (in a way) 2 commitments...one to the back and one to the camera....we will see which one holds up....again: the hasselblad camera buyers just got seriously burned.....so i am not sure how they feel about another commitment....
for the rental market: i am sure that THE most rented combo in the US is H with a phase back....this won't change..the rental houses will ride their H1/2s into the ground.....and photographers and ADs(!!!!) will still demand a phase back.....
or phase just rolls over and dies.....
