The announcement on Hasselblad's page has like this...
"
Hasselblad x ALPA: Sharing ExpertiseHasselblad and Swiss camera maker ALPA have formed a collaboration allowing an unprecedented exchange of expertise and technical information. With a shared philosophy of superior design and precision engineering the partnership grants ALPA access to Hasselblad’s technical documentation regarding their cameras and lenses. It allows ALPA to adapt its technical cameras to achieve optimal system compatibility and integration.
The partnership enables
optimised integration of all ALPA technical cameras with both Hasselblad digital backs from the H System and CFV as well as Hasselblad HC/HCD lenses."
There already was a Hasselblad H mount available for ALPA cameras, but it seems that Hasselblad is now providing to ALPA the full latest interface communication for the lenses and the backs, as it is on the H6D camera...
EDIT: The will of Hasselblad as to provide solutions for all tasks related to imaging by collaborating with companies that specialize on other than "conventional use of a DSLR" is more than obvious...
Other than that, ALPA is presenting a ton of new products at Photokina that will undoubtedly affect the future of high end photography:
