It looks like it pulls out then flips up. Likely to keep the EVF as flush as possible to the body when it's in the "normal" position.
Yes, I would much rather this that a tilting screen.
It seems a bit overkill to have both the screen and the EVF tilting. As a photographer, I would far prefer a tilting EVF than a tilting LCD screen.
The body in the drawing looks like an R6/R6m2. Maybe it was already implemented in one of those prototypes for testing.
Maybe two Canon departments, that don't know from each other?
Ummm... Just so you know, Samsung had that very feature on their short lived NX-30 Camera introduced in 2014... Appears Canon is 9 years late.
Two points there. One, the new patent must have sufficient differences to have novelty compared to prior art. The devil is in the details, so even something that looks similar can easily be different enough. Two, when CRguy and others report these news items as 'Canon patents' it generally means the patent has published, which happens a fixed 18 months from the date of application filing. It doesn't mean the patent was granted in the form it was published, so if upon review the examiner determines some of the claims are not novel, they will be rejected.
I suspect that extension tubes were never very popular, and they're likely pretty far down on Canon's priority list for the RF mount. I think they're of even less importance considering that Canon is adding semi-macro capability to many lenses that would have formerly have been used with tubes, e.g the RF 24/1.8, 35/1.8 and 85/2 all go to 0.5x native magnification.
