A macro lens was to be a part of the EOS M's future, and we now see what I think is our first patent for an EF-M macro lens. This optical formula is for an EF-M 55mm f/3.5 Macro for an APS-C sensor.

While a full frame mirrorless solution from Canon appears to be in the works, we haven't heard anything about what kind of mount the camera would have.
We are expecting some EOS M announcements in the first quarter of 2016.
