We have been told by a source with a pretty good track record (but not perfect) what we can expect the rest of the way from Canon in 2019.
First up, it's not a secret anymore, but we're going to get the Canon EOS 90D, a camera that will apparently replace both the EOS 80D and the EOS 7D Mark II. With the latter line being killed off by Canon.
We're told to expect an announcement near the end of August.
Apparently, a new EOS M body will come at the same time. It has been described to use as “very well specced” and “aggressively price”, with Canon wanting to show that the EOS M lineup isn't dead. No specifications were provided to us.
No other EOS M cameras or lenses are scheduled for 2019.
What about the EOS R system?
The same source tells us that a new EOS R camera is coming later in 2019 and that it is a “head scratcher”, and not at all what anyone is expecting. I have no idea what that means at this time, but we hope to hear more soon. What sort of niche market could benefit the EOS R?
There was nothing mentioned about lenses for the RF mount, but I assume the remaining 5 RF mount lenses need to be officially announced and shipping before we see any others.
Genius! All ILCs up till now have been heavier than water, an issue that has proven costly to many a careless photographer. Canon is going to launch a revolutionary (remember, that's what the "R" means!) R body that literally keeps afloat!

They also had a patent for a swivel grip which would give it a camcorder feel.
