I'm guessing they will add that dual pixel technology to improve the AF, and then they'll have a winner. As good a quality as a xxD line in a smaller package plus you can use your existing lenses. This "enthusiast" market, though, is small compared to the smartphone shooters who want to foray into higher quality images, and really don't want something bulky like a DSLR. That's the market Canon wants, and I think their timing is good.
I have to agree.
As soon as I saw the dual pixel 70D my immediate thoughts where the technology will go to a shutter-less medium-high end camera. The EOS-M2 of course.
When the price went down I thought about the EOS-M for my wife, and maybe start looking at selling the 50D body we have. My primary body is a 7D. But with the introduction of the 70D my plans were very quickly scuttled.
The dual pixel sensor would be perfect in the EOS-M, and for a $600'ish camera the EOS-M2 with the sensor from the 70D and the same form factor of the EOS-M, would make a great camera. IMNSHO of course.
So, sadly for my pocketbook, I can see a EOS-M2 and a 7DII in the house in the next year or 2.
We will see, speculation is a fun sport. And guesses if Johnny Football will be playing this fall???
