More interestingly, what features would you like to see included?
I would probably buy one if it had a manual zoom ring. I don't like power zooms and only tolerate my S100 because I can program the control ring for step zoom. A real manual zoom ring on a G2X would be infinitely better.
Other features I'd like would be touch screen controls and a faster lens. But then, I suppose that's retty much what the EOS-M is.
