A new Canon Japan patent shows the optical formulas for various RF 50mm f/1.4 designs as well as an RF 35mm f/1.4. This patent deals with increasing focusing speed when using lens designs with large diameter elements.

I don't think any of these optical formulas will become products, so the dream of a new 50mm f/1.4 from Canon probably won't be coming true any time soon.
