I agree. I don't find that the K-5/7's amount of buttons is overboard, and I guess I just don't see why you'd want less, on an advanced camera marketed towards very experienced users. For one, it'd be a completely different interface that they would have to learn to adjust to, and secondly, you then have all three controls that must be adjusted by the same hand separately, instead of simply turning a wheel that your finger/thumb is right next to anyway. It seems like it would be easy to adjust the wrong thing with three concentric dials very close together, and slower to adjust considering your left thumb/forefinger have to do all of the adjusting.
Also, with longer lenses that need to be supported further from the camera body, this makes even simple adjustments very cumbersome, where the digital wheels are still simple as pie... er.. if pie is simple, that is.
