Good questions. #5 would certainly be a concern for me (I like to have RAW for all cases)

I guess thinking about this a bit more, even if Canon did add Pixel Shift to the R5, it seems highly unlikely they would add a new RAW mode for the new pixel count images that would generate.

What new pixel count? If they are shifting one pixel to get around the Bayer issue, you'd have the same number of pixels. Because of the AA filter, I doubt a half pixel shift would gain anything useful. Someone can correct me if I'm wrong about that.

As you wrote, there would not be a need for a new pixel count or type of raw; just tag them as going together. It would be like focus or exposure bracketing.

That would mean it isn't performed in camera like many of the competition. Some (Panasonic?) seem to combine with IBIS to get higher resolution hand held.

Given this is a rumor of a rumor of possibly a rumor we don't know what, if any major updates will be coming to the R5.

The half-pixel shifting is not to get around the Bayer pattern. The shifting would be half a pixel sensor (i.e., half of one color sensor). If it were to address the Bayer pattern, it would shift by a whole "pixel." Even with an AA filter, there will be some effective resolution gain. Likely about 1.5x in each direction and not the full 2X. It is roughly the same thing done by many projectors today but in reverse.

With some recent posts regarding AA filters I had considered that the design or requirements for this are likely part of the pipeline when deciding a camera would have this type of feature (increasing effective resolution).
