I think you meant to write "revolutionary" not "evolutionary" in your past two posts Guy.If anything this Photokinia it's the lower end of the market is where the evolutionary products are coming from. Now we need to hear the rest from the high end side. Leica and Pentax need new sensors and I think we may just see CMOS chips in both of them.
I'm not sure where the notion that "revolutionary" photographic industry camera technology would come from the medium format sector? When has that ever been true?
There may be innovations with-in the category itself ... like I consider the Contax 645 to have been, or some may feel the Hy6 to be, (or the S2 if we stretch the definition of MF). I also feel Hasselblad's True Focus APL to be just such an innovation with-in the MF camera category.
However, most if not all photographic industry "revolutionary" camera innovations have come from the smaller formats ... and that, as you mention, remains true today I think.
For example the trail blazing APSc sensor cameras with mirror-less technology, probably a FF one soon if Sony comes through. Why wasn't the D800 mirror-less or SLT? Or the Canon 5D-II? It's not like those companies don't have the capital and resources to have made it happen. Why didn't they?
It isn't beyond the imagination that one of these MF companies will do something bold, but to put all their eggs into one basket is a pretty risky move if you ask me. Leica did it backed up by the M system. What would back up Phase One or Hasselblad if a "revolutionary" as defined by many here, wasn't accepted by the marketplace?
Personally, I'm not willing to back "revolutionary" ... what I want is a demonstrably better version of what I have now, and then I'll consider something off the wall if it replaces something else I already need and use.
