We won't see raw internally for video on any Sony cameras unless the whole RED patent thing gets resolved, or they come up with their own semi raw like Canon raw lite. I do expect the A7R V to have 8K internally though. It will have the megapixels for it after all.
I think you are confused about one being superior to the other. A lot of it is down to personal preference. For people like myself who want their stills cameras to shoot great video AND be mirrorless it's taken Canon 6 years to bring out a full frame mirrorless 4K crop free hybrid after Sony's made the first with the A7R II. In fact the R5 and R6 are their first mirrorless cameras worth looking at full stop. Personally I think the Sony colours are great, and they've gotten better recently, also the new menu system that made is debut in the A7Siii is great.
Canon have made a superb comeback and it's about time! :)
Yes they absolutely can put a variable ND in their mirrorless stills cameras if they wanted to but it would be at a cost. The IBIS would have to go. There's no space for both. In fact they haven't worked out how to do both yet hence the FX6 has no IBIS even though its in a bigger body.
But Sony can’t do what Canon did. Hardly anyone has Alpha/ Minolta lenses whereas most Canon users have EF glass. Nikon should have done it though.
Here is part two :)
Since when was the A7SII a “prosumer” camera?
Utter poppycock! The colour science is just fine. I have used it to part shoot countless hours of high end broadcast documentaries. Anyone who says that needs to learn how to grade.
