Same old 18GB sensor?
You clearly didn't read the first post ...
I'm sure it's just a variation of the same , tired, old, 18 GB sensor that is in so many of their cameras. If they really had anything new do you think they would debut it in a powershot? Why not the the 70 or 7D? The sensor will grade out the same, nothing new here. Sensor innovation is not coming from Canon. Have you seen what Nikon and Sony are putting out in this sensor size? For less money?
