Sony A750 Rumor: 14.6 megapixels

According to neutralday.com, they received an email claiming the A750 will be full frame, 14.6 megapixels, 12 bit camera. More specs are given, but the specs are for the sensor only, and if correct, the 15.2 fps scan mode would likely mean this sensor wouldn't support a video mode without a lot of processing on the back end to generate the extra frames.
