This is a good review. I can actually feel you trying to give Canon some love.
I was genuinely stunned when the EOS R was released and, in every functional way, it is still the same old Canons I had before. There's nothing improved upon. When I buy a camera, it has to replace a previous model and the EOS R in no way, shape, or form replaces anything that came before it and that is not promising for the future.
If I want it to replace an 80D, it has to shoot better 1080p. Nope.
Replace the 5D4, it has to shoot better 4K or better stills. Nope.
As an events/wedding stills camera it's not any better than the 5D2 (the SAME burst rate w/ AF) unless I want to be tweaking CR3 dynamic range in post all day (which I don't).
DPAF and Andrew's EOSHD CLOG extended my loyalty to Canon (I've got half-a-dozen EOS bodies, just as many L-lenses, and double that EF and EF-S lenses) but Fuji has the X-T3 and that body and system (refined eye-AF, film simulations, F-LOG, and low rolling shutter) has the potential to wipe away what little advantage Canon had over this market segment.
Even if Canon releases a higher-end Pro-R that gets the feature set we assumed (hoped/prayed) was coming for years, now, it's still going to be north of $3000 USD. I sincerely doubt that feature set on such a hypothetical camera is going to be better than what is on the Fuji X-T3, which is available now and is half that price. Heck, I outfitted my X-T3 completely for documentary shooting (three primes, booster grip) for the same price as the EOS R body alone.
