I have been told a couple of times now that 2022 is still scheduled to be “The Year of the Camera Body” from Canon. This means we should expect many new camera bodies announced this year. For the moment, it sounds like most major releases will happen in the 2nd half of 2022.
While I haven't been told specific models, I do have a good idea about what to expect from Canon.
I also expect replacements for both the Canon EOS R and Canon EOS RP. I don't believe either camera will get a direct replacement and instead we'll get two new affordable full-frame cameras to fit below the Canon EOS R6.
I also expect at least one APS-C RF mount camera to be announced, more on this in the near future.
A high-megapixel RF mount camera? I haven't heard a thing about in a long time, but I do believe it's a worthwhile niche for Canon to go after.
The Canon EOS R1? While it's definitely being worked on already, I do believe Canon wants to collect as much feedback as they can from the Canon EOS R3, and I don't expect it to be announced until the 4th quarter of 2022 at the earliest.
The chip shortage may obviously affect product availability, I don't think Canon is going to hold off many product announcements going forward. The chip shortage will eventually end, and it would be smart to continue to announce new products so they can hit the ground running once the challenge has abated.
