Our problem as Canon users is, that I expect Canon will not be able to deliver a sensor+electronics matching the current Nikon D7100 sensor in terms of IQ. Not in resolution (20 vs. 24 MP) and probably even less so in DR across all ISO settings starting at base ISO nor in Hi-ISO Noise. At best, I expect the 70D sensor to come in "only" 1 EV lower in DR and noise across the entire ISO range.
Canon uses the same 18MP sensor in their ASP-C cameras since 2009. It was very good at that time, bug aged since then.
I don't think they weren't developing new sensors. I may accept that they couldn't develop as good sensors as competitors, but for me, the 20MP tells something: it must be much better.
Why? They must have developed a few different sensors in size, and they tested all. After all, they decided to use a 20MP one in the 70D.
Why? Maybe because their 24MP sensor doesn't have as good IQ as the Nikon one. But the 20MP one, I think is at least as good as the one in Nikon.
Othewise, what would the market say? Lame Canon couldn't even develop a sensor with the same IQ as the one in Nikon that has 25% more pixels.
We'll see on next Tuesday.
