The next EOS-M camera apparently will be called the EOS-M2. There may be two models. One is a basic model and the other one is a higher end product, complete with a viewfinder and new AF system. Both models will feature the DIGIC 6 processor and may share the same 20MP APS-C sensor as the recently introduced EOS-70D camera.
Canon may also announce a few new STM lenses, including a 55-200mm and 18-135mm zoom, and maybe a prime lens as well. For some unexplained reason, Canon is not releasing their recently introduced EF-M 11-22mm f/4-5.6 lens in the United States. Look for Canon to make a splash with the relaunch of the new EOS-M models and try to re-energize this line of cameras.
