We've been saying for quite a while (since May, actually) that a new breed of M camera was coming - information that we received from a pretty credible source. However, we haven't been able to get any new information or further confirmation for a while now. When the Leica SL (Type 601) was introduced, it had us second-guessing if that wasn't it... But we don't think so. This new registration of a Leica M (Type 262) camera is renewing our faith in this original report that a new M camera is still coming.
Update (11/19/15):
We have the specs of the camera being released today!
...And it's here - the Leica M (Type 262) camera!
