Without IBIS no Pixel-Shift. So R8 is out, but my guess would be that this is a premium feature and will not come to R6 and R6 II like SONY does it.
Where did Canon admit that the overheating is a firmware cripple? Sorry, I missed it.
Many test were done back when the R5 was first released. Running the camera off AC power in full 8K it could run for hours without issue. Battery door switch defeats. Just tons of things that people did to show that the overheat was indeed caused by a firmware cripple… Canon maintained that the limitations were real and not artificially imposed via firmware. Well, if real physical hardware limitations, then the release of firmware 1.6 could not have magically fixed the R5 overheating issue… Yet it did.
Two Things to say: 1) Although it is logical to assume that if such functionality works in the R5 it would work as well for the R6 II, I seriously doubt Canon would allow this to happen as it would dilute the appeal of the R5. Think about it this way, if you needed a high-res camera, why would you fork $3900 for the R5 when you could have a very similar resolution from the R6 II .
I don't shoot movies and haven't followed the issue closely, but one thing I'd mention is that if Canon gives an ability officially, it has to work right and not damage the camera via overheating or what have you. It's possible Canon didn't have the data, or did have the data and it failed the internal criteria of the time. So if it's been allowed since then, it could be an engineering change such as new algorithms that use less CPU and thus make less heat. Or perhaps a new business rule as to reliability requirements, or a business decision that at this point in the product cycle they'd rather make more sales even it means more warranty repairs. Finally I recall part of the problem was heat from the memory cards? I can't recall, but if so, perhaps new memories over the last few years include some which make less heat?
