Is Canon planning to make f/1.2 the new standard for all of their L prime lenses up to the focal length of the RF 85mm f/1.2L USM?

The Canon RF 35mm f/1.2L has been rumored for quite some time and has appeared on our RF lens roadmap since the beginning. There have also been previous patents for an RF 35mm f/1.2L USM.

Canon News has uncovered another patent for an RF 35mm f/1.2L USM optical formula, along with two other f/1.2L prime lenses that would be highly desired, an RF 24mm f/1.2L USM and (oh joy!) an RF 28mm f/1.2L USM.

If all of this comes to fruition, this will be a very hard set of prime lenses to beat.
