UPDATED: Canon representatives have confirmed they have no current plans for an announcement in the United States. Canon Japan and Canon China both outed the anticipated EOS M2, but there hasn't been (and won't be) any such announcement from Canon USA. The EOS M was met with a rather tepid response stateside when it was first announced, and even after firmware updates and a price drop, it hasn't had much traction.
The most noticeable addition is the "Hybrid CMOS AF II" which hopefully offers a better experience out of the gate than the original M did. Get a full rundown of the EOS M from Canon Rumors or the press release from Japan (which you can translate in Google Chrome).
What do you think? Will we see it in western markets, or will the less than great sales figures have Canon looking to place the interchangeable lens camera only in their Asian markets?
