"According to my sources Sony has chosen to use a completely new sensor for the upcoming professional SLT (Translucent) camera. The sensor will have 24 Megapixels but don’t worry, I have been told the noise performance of the sensor is equal if not better than current 14-16 Megapixels Sony sensors used for the NEX and A33/A55 cameras. It will feature the highest resolution APS-C camera on market (The Canon 7D is on top with the 18 Megapixel sensor). The Sony A77 will be released by mid 2011 because Sony needed time to develop an almost perfect camera. There will be many innovations (Paul Genge of Sony UK said that “ “). It will have an improved BIONZ processor (based on the current A33/A55 processor), micro af adjustment and record 1080/30p, 720p60 and 720p30"
Promising if true.
