[ Copying a post I did in a new thread in "EOS Bodies" rumor forum, but maybe it gets more views/response as a comment here

First, I'm sorry. I haven't read all comments to all posts here on CR. So this might have been mentioned before. But someone on dpreview saw a possible hint of what to come in the little EOS R1 teaser video.
First look at the R3 teaser video. In hindsight it clearly hints the Eye Control AF feature.

Then look at the red pattern "flashed" over the EOS R1 title in the R1 teaser video:

"Quad Pixel" sensor design?
Besides for better autofocus, if true, could such a design also be used for the rumoured dual-gain support?
One pair of sub-pixels with "high" gain, and the other pair of sub-pixels with "low" gain?
I don't know much about dual-gain sensor designs, but I assume the advantage would be higher dynamic range.
