While I agree that buying a $510 K-x makes more sense than a $800 K-r at the moment, I also feel the improvements to the model are part of the natural evolution of the product. I'm not so sure the ISO25600 option is going to lure too many in, but the speed increase (6fps vs 4.7fps) with the updated AF makes the K-r a little more attractive to sports-minded people.
