Is Rollei (or Frank & Heidecke) still around as a vendor?
Yes, but now as DHW (no more Frank & Heidecke, but same people apparent and same building)

http://www.rolleiflexpages.com/The Hy6 is an interesting chapter with an unfortunate history. So far I am impressed by the Hy6 and on basis of one lens the 80mm Xenotar AFD it is a camera and system that seem far better than what I experienced Mamiya.
If we look aside from market and business and only on camera and system, the Hy6 seem as the best camera body out there for digital back (plate cameras such as Alpa, Arca, Cambo etc are of course a complete different type). The Hassy V is too old, the Hassy H is a 645 and closed system, Mamiya 645 is too clunky... and Hy6 and all lenses for the system are seemingly of quality and character, and made in Germany. The lenses are perhaps better than Hassy V, also because there are top Schneider lenses alongside Carl Zeiss.
So is it an ugly duck? If anything because of an unfortunate history, not due lack of quality or capability. Rights to Hy6 apparent are with Leaf, thus essentially Phase One. It seems with the qualities of the system it sort of begs to be picked up an marketed... Meanwhile Phase-Mamiya are assembling new Schneider glass in Japan. One may wonder why recreate a wheel instead of using one that is already run and can roll smooth if driven such? The Rollei lenses smells quality and character. What will happen? Hy6 does seem as good opportunity for an alternative camera to Phase DF... Phase? Leaf?
Actually the Hy6 seem as what a modern version of Hassy V could have been... kinda interesting
