Patent: Canon RF mount Big White Lenses

I had a hope Canon will do a mount conversion service on the EF 600mm f/4L IS USM III and EF 400mm f/2.8L IS III, but if they are going to introduce new lens probably they are not going to do mount conversion on the EF version
why would you prefer to mount convert your lens? Isn't it so that one day when you decide to sell your lens, there are more potential buyers for EF than for RF mount because EF can be adapted to other systems as well? Wouldn't it more beneficial to purchase EF-RF adapter and leave it to the lens ( = more options in future)

Coming next: the 1DX-bodied R1 with a huge battery, fast stacked sensor, 20fps @ 36mpx @ 14bit, low-light-king-of-the-underworld, and...
NO video(!!!), and NO low-pass filter!!!

(Disclaimer: this is not a rumor... just me daydreaming...)
