I have finally posted a few shots from the K-5. Yes, it does indeed show off the now-legendary 16Mpixel Sony sensor: this is a straight jpeg, no adjustments but cropped to reduce clutter from the scene. ISO 6400 is an acceptable speed for this camera, especially for simple snaps. Had I really been trying it could be a better image, but this passes the PGE test (Plenty Good Enough!) easily.
