Simon97: I'm most interested in the "newly designed" 20mp sensor. Sony went from the excellent 16mp sensor to the 24mp sensor and now the 20mp shows up. It could possibly outperform the 16mp sensor in noise levels with the addition of a bit more resolution. It may show up in Nikon, Pentax and Nex cameras.
The 24MP sensor came out out several months before the 16mp sensor for a57. The 24mp was introduced with the A65 & A77.
