Canon Patent Application: 90mm 2.8 and 100mm 2.8 Macro for the Canon RF
Here is a patent application we know Canon is most likely working on. Having a 100mm macro is pretty standard for any ecosystem, and the RF system will certainly have a 1:1 macro lens around 90 to 100mm in focal length.
This patent application illustrates two different lenses, one at 90mm and another at 100mm. Both with IS.
Because of the small back focus (BF) these embodiments are certainly discussing a full frame Canon RF mounted macro lens.
