However, pixel to pixel read-up variation has always been the bane of CMOS design.

Canon may now have tackled this at a wafer fabrication level, rather than calibration look-up tables, as well as using a full field micro-lens to achieve a few Db gain with similar noise reduction.

In short, I don't think it's all smoke and mirrors.
I remember the presentation.. I was there . Really appreciate the insights though.. it's exactly the kind of information/discussion i was looking for. it's more than smoke and mirrors, but my bet is still on though.. it's not two stops of improved sensor performance either!
