I am intrigued by the "ISO range is 100-25600" spec. If that is not an expanded range, it would probably be a new sensor. The 60D lists its 18MP sensor range to 6400 (12,800 expanded) and uses a Digic 4. If the 25600 is expanded, then it could be the same sensor just with better noise reduction applied via Digic 5...
look, it's simple.
they got the same old 18MP sensor from 2009 and put some AF points on it, put this together with the DIGIC5 and they created 650D. then, they created EOS-M, this is the same as 650D. then, as too much sensors were produced and 650D is outdated and EOS-M didn't work fine, they created just another body for the same old sensor, this EOS-B. hopefully they will get rid of the stock of this sensor.
they are delaying the new ASP-C sensor (70D, 7D2, then 700D) because they want to sell as much from this ancient sensor as they can.
