ISO 64 – 25,600 seems a bit off, unless those are the good ISO's. Like if it does ISO 25,600 as good as a R5 then it is a-ok with me.

My previous guess on the R1 specs had 20fps @ 45mp with limited buffer ie the same as R5. With real time downsampling to ~20mp would mean unlimited buffer at ~20mp similar to current 1DXiii. If it means 2 x Digic X then that also makes sense to reduce hot spot heat generation by reducing individual clock speed and heat spreading through the body.I do not believe R1 image and video resolution will exceed 6K.
The 1DX III main selling point is the infinite buffer.
Large image sizes make that extremely difficult and for people who take thousands of pictures bigger files cause more problems than they solve.
If the rumour is correct then Sony is developing the sensor and Nikon is tweaking it for their purposes eg ISO64 base. It wouldn't surprise me that Sony is developing a sensor to compete with the R5 to match 8k30. They heard the rumours and Canon marketing drip feeding the specs over the last ~8 months. Whether Sony/Nikon can have a production camera based on such a new sensor within 18 months is a good question. I expect that Canon really surprised the competition with the headline R5 specs. The key challenge for Sony/Nikon will be to meet the R5 specs but with better thermal management.Unless I am markably mistaken, Nikon design their sensors have have Sony produce them in much the same way Apple and AMD have TSMC produce their chips.

That’s my believe as well. The downsampling would also enhance ISO performance. The R5 has set the tone for high end mirrorless systems.My previous guess on the R1 specs had 20fps @ 45mp with limited buffer ie the same as R5.

Not sure that 8k/30 video is the prime spec but 33mp frame grabs is likely to be more useful for sportsNikon can shove it out with the same thermal management and it would be fine for the 22 seconds of 8k footage I'll take of Princess Arch Mage Willow Hissington the Third before I go back to my iPhone for video.
Then maybe the water is not cold enough?Not sure that 8k/30 video is the prime spec but 33mp frame grabs is likely to be more useful for sports
From my perspective, I use 4k120 much more often for underwater video and has the same overheat issues as 8K30

The water temperature is about 15C in Sydney at the moment... quite chilly even with a 5mm wetsuit and vest/hood when spending 2 hours under. Using a partial vacuum (roughly 7" of mercury) in the housing to ensure good sealing means convection is very limited and conduction is limited to the plastic tripod mount. Radiance/radiation from the housing shell would be the main method I think with about 20C temperature differential. I am generally limited to the CFe card size than overheating at the moment. Need to ensure I don't accidentally forget to turn off the record button properly!Then maybe the water is not cold enough?

A very interesting review! Canon Europe used to have the only official website showing approved CFe cards for the R5 but the link has broken. Canon Asia and Canon US have the same information....You should try the 2TB Delkin, if you haven't already. Cheap for the $/GB. Among the fastest, although not rated for high bitrate video apparently. Did a testing comparison of the brands... https://camnostic.com/cfexpress-cards-comparison/
Before switching from film to digital, I checked the offer on the market.Indeed, both is probably the way to go. I can bet Canon will have the tilt shifts that whisper to me.
