Japan Patent 2021-18277A shows off a bunch of optical formulas for various fast prime lenses for the RF Mount.

Included in this patent are two 24mm f/1.4 optical formulas, as well as an RF 28mm f/1.8 (Yes Please!), a 35mm f/1.8 and a lens that would likely be quite popular, an RF 50mm f/1.4.

I think it's safe to say that we will see an RF 24mm f/1.4L USM at some point in the next year or two. I've been doing this site for 13 years now, and we're all still waiting for a new 50mm f/1.4 lens from Canon. I can already see the “Shut up and take my money” memes.
