Anvh, you like it or not, medium format is their pro system. This won't change, and your input is irrelevant.
Don't tell me you don't know about the OM-G, erm, OM-D (Oly's marketing must be affecting me, I keep calling it that way
). Is exactly what you're asking Pentax to do: short registration distance, "pro" mirrorless, can use 4/3 lenses with stinkin' adapters (which coincidentally aren't free and you'd get slow AF) and with those, you even have f/2.0 zooms. Tell me, are they competing with Canikon's pro FF?
I see you're not even sure if you used Pythagoras or not... for me, the conclusion is clear: you made that up.
By the way, one does not simply scale down the registration distance; there are many areas that are more or less constant: shutter space, the protruding part of the lens (more than 0.8mm, as you can see), tolerances...
And about your solve-it-all technology, I'll quote from that page: "Switches between reflective and transparent states in seconds"
Wow. I'm speechless.
