FWIW, Samsung is entertaining the idea of a 500 MPX sensor because they think it will then match the human eyesight. With the current technology, it'd have to be ~ 350 mm2, which is the APS-C format.
My point about high resolution sub-1" sensor is that they allow for a stupendous reach. Nikon Coolpix P1000 is about eight inches long with a full zoom extension, which gives a 3,000 mm focal length equivalent. At the moment, the camera is somewhat of a novelty but it can easily be turned into a high end product for wildlife/BiF shooters.
