You can also expect Phase One to support and provide the Hy6 camera, which therefore makes it 100% of the independant medium format back makers. The only excpetion being, of course, Hasselblad.
Michael, only the senior mangament of F&H, Sinar and Leaf(and the companies' lawyers) have any real idea of what is in the fine print in the contracts between them as to who has what rights to distribute the Hy6, whose backs will be compatible with each company's version of the Hy6, and who has what rights to specific quantities of production. And I can assure you, there is a LOT of fine print in those agreements. I would expect that neither Thierry nor Yair has seen the actual language. These players are every bit as focused (and anxious)as Hasselblad is in protecting their position. They really don't care about Phase and their owners having happy homes for their backs in the future. They are all conspiring individually and probably collectively to lock Phase and the owners of its backs out of a camera platform, so they will switch to Sinar or Leaf. Not what you want to hear, but a fact of capitalistic life. And if the Hy6 starts off "open", please don't bet the ranch on it staying that way.
We can all check in next summer and see who is selling the Hy6, whose backs go on it, what integration has beeen achieved between the camera, the lenses and the backs, and what the cameras and lenses cost(WOW!).Of course, all of this may become an amusing footnote if Canon comes out this Spring with a new camera in a new format that competes even more directly with the MFDBs at 1/3 to 1/2 of the cost. It will be a fully closed system, but everyone will happily go running off to buy it without a hint of protest, and Rollei will continue to Rollei.
