I remember reading somewhere that the current firmware upgrade for the H2 adds compatibility for the 28mm lense.

Not the H2, John, just the H2F, which only works with Hasselblad digital backs.
If you like the idea of a 28mm lens, actually if you like the idea of a 28mm lens which can be used with a full frame 645 sensor (or film!), consider the Phase One Camera System. We're working very closely with Mamiya on continued development of this system, and I believe a more and more compelling argument is being made for it. A vertical grip is on the way as well as Leaf Shutter lenses and umm, some other things.
Heck, you don't even have to put a Phase One back on it, you can use Hasselblad or Leaf or Sinar or....
But you might seriously consider putting the Phase One DB on it.
