We know about the 4 lenses that Canon is going to announce soon (we're not sure on the exact date yet), and along with those lenses, we'll be seeing the replacement to the Canon EOS M10 being announced. We're not sure if it's going to be called “EOS M20” or not. Expect specifications that are similar to the EOS M6/SL2 in a small form factor.
Nokishita has confirmed the EH31-FJ face jackets for the EOS M10 successor are on their way. It looks like you're going to get 9 color options.
There has been no mention of any new EF-M lenses coming alongside the new EOS M camera, but there's a chance that could change.
We haven't heard anything definitive about a new prosumer PowerShot camera(s) coming.
