In addition to a new flagship EOS R PRO mirrorless camera, Canon is also rumored to announce at least two new EOS M cameras in the first half of 2019:
A new Canon EF-M 32mm f/1.4 STM lens is also expected.
After the EOS R announcement, it is not clear how Canon will develop their mirrorless strategy in the future since there is no clear upgrade path from EOS M (APS-C) to EOS R (full frame).
