K mount flange distance + mechanical contacts eliminate it.
Jumping onto an existing EVIL mount would be smartest in my opinion. I would like to see how pentax goes competing head to head on features/ ergonomics etc!
M4/3 or the Samsung mount are most likely.... Of these I would like to see the APS-C retained so my vote is with Samsung. Not entirely unlikely given previous cooporation.
WR would definitely be an advantage...
I dont see why people think it is an insurmountable engineering problem to have a fully electronic mount for the mirrorless camera but still retain aperture and focus control. Any adapter for a kmount lens to a mirrorless camera is going to be of substantial thickness (look at the sony alpha to nex adapter, which does have aperture control).

Anything for Pentax would be of similar dimensions. There is plenty of room in there for 2 micromotors, one to operate the aperture linkage (as sony has already done) and one to run the af screw. It would be more expensive and probably pretty slow focusing if it had to move heavy glass around, but I think alot of people would buy it if that meant they could still use their limiteds on it. And of course, using any of the sdm lenses would not be a problem as long as the adapter had aperture control. Samsung, panasonic, and olympus all make af pancake lenses that are not any larger than that adapter that squeeze in focusing motors along with lens elements and aperture motors. In fact, someone posted a video on dpreview where some guy in Korea had converted a samsung pancake lens for the nx10 into a working autofocus adapter for nikon FF lenses, and it had to move the entire FF lens back and forth. People assume its not doable just because no one has done it yet. But none of the other manufacturers have quite the incentive to preserve backwards compatibility that pentax has.
