That's true, but the bugs combined with the somewhat slow performance of the camera (again, no smooth feed to the EVF, no burst in silent mode for right now) says to me that overall Canon was not quite ready to enter the market when they did.
Right... so Canon should not have entered the market in 2018 but should have entered the market in 2020 with the camera you want without releasing anything else prior to that. The R isn't for you, and the RP isn't for you either. Yet, you're staying with Canon because Canon is showing what it can do with RF lenses. And that is where Canon is smart. It couldn't produce a mirrorless 5D4 killer in 2018, but it has it's foot in the door for FF mirrorless. It stops a lot of the bleeding to Sony/Nikon with its initial launch either because the launch products are sufficient for some people or because people can see the potential of the system in a couple years.
The R doesn't replace my 5D4, but for a lot of cases (non sports), I prefer it to the 5D4. But the R gives me a unique backup/coprimary body and gives me access to some fantastic RF lenses. Once the mirrorless 5D4 killer is released, then I'll be swapping out all my workhorse EF lenses (16-35,24-70,70-200 and 100-400) because there will no longer be any reason to keep EF bodies.
