Originally posted by Larrymc Have you ever handled a K-3/K-3II at all? If you had then you would know the difference. Every control falls readily at hand. For instance when I move my forefinger from the shutter button to the front e-dial I don't have to lift it off the camera and bend it at a weird angle the way it appears you have to do with the KP. Its just a smooth quick movement. Reaching the ISO and EV compensation buttons is a slight move back from the shutter button. Other buttons are just as easily accessible. I haven't handled the KP as of yet but from what I have seen its just not as ergonomically efficient a the K-3/K-3II. It (KP) can definitely autofocus better and does have better IQ but I'm willing to wait to see what comes out from Pentax. My 4 yr old almost brand new K-3 still has me loving it.

I imagine that when the K3 III comes out it will mimic the KP/K-1 style (ie third control wheel), albeit with a body size that is close to that of current K3 cameras. I imagine improvements over the K-P to be deeper buffer, little tougher build, probably a little faster frame rate, dual card slots and will use the larger battery in the body, not just the grip.
Body styles do change over time and Pentax tends to have an evolutionary approach to them. At the same time, if things aren't too different, it doesn't take long to pick up little differences and for it feel natural.
