Guys,I got an update from one of the canon staff that they had received email the new firmware will sort of fix the overheating issue with longer recording and faster recovery time.Finger cross,I still haven't place my pre order yet.
Some how I missed this, but that would be awesome. These cameras are so incredibly well designed and well performing. Mitigate this one flaw and there's nothing that can compete at their price points.
I don’t understand why physically having the cards inside would make any difference assuming the camera isn’t writing to the cardsIt would seem there should be a way in software (new menu item) to disable any use of installed memory cards that could accomplish the same outcome without having to physically remove the cards?

Also should be able to record to a smaller , cheaper 4K recorder without a monitor screen
Yes, this is a good explanation.Just like a computer, the cards share a data bus with the processor, the internal memory buffer for continuous shooting, other cards, etc. so the card is always active. It doesn't turn off, it has to monitor the bus for any data directed its way and process it when that happens. This means a portion of the card is always active.
Just to follow up on this, I did a bit of googling and came across this...Just like a computer, the cards share a data bus with the processor, the internal memory buffer for continuous shooting, other cards, etc. so the card is always active.

No that’s not what he said at all.
Much higher resolution lenses will not realize close to potential sensor resolution so at best, using his rough rule of thumb, you’d end up with maybe another 30mp or so, or going from 70mp with current lenses to 100mp with new generation much more expensive lenses.
Mind you the entire idea of constantly moving forwards in this is, in my opinion, flawed. For movie/video use we intentionally use shutter speeds to blur each individual frame, 4kHQ and 8k demand higher shutter speeds to maintain the detail and have a distinct look far away from the ‘cinematic’ look so sought after by influencers, YouTube experts, and forum hobbits. For stills at ±50mp we already vastly outstrip the possible resolution of most output apart from people with the need to use extreme crops and whilst there is a user base with that requirement it is not the norm or close to it. I am a generalist professional photographer and sell prints up to 24” x 36” and I use 20mp. Sure I could use more resolution on occasions but I see little benefit 99% of the time for pros or amateurs or enthusiasts that warrants the expense of another new round of lenses and cameras, we passed the point of diminishing returns on mp a long time ago.

http://www.farnell.com/datasheets/2815914.pdf - which is the engineering spec for a Delkin CFexpress. If anyone doesn't want to read it (don't blame you!), there's three interesting points...
First - the heat sensor is on the CFExpress card for the Delkin - presume others do the same. And this will control when the speed is throttled ie Canon doesnt control it, but presume they get feedback from the card.
Second - Delkin supports APST, ASPM & L1.2 power management. Which essentially allows the card to go into a lower power mode when it is not active, but at the cost of delayed wake up time. Doubt it is more than a few seconds.
Third - the Delkin has different operating Power States, which consume less power while still operating (there is a light & heavy throttle). The default state has no throttling. Alas the paper doesnt state how much light throttle does - but if the cards can do 1000MBps write (on the higher capacity cards) then a mild throttle may not impact write performance (believe the highest 8K modes need 325MBps)
I could not easily find if Sony, Lexar and Sandisk support these - I guess one could email to find out, but equally importantly, one hopes that Canon doesn't support the lower power modes nor the power management in DryOS and therefore there could be some benefit gained from implementing them.
Or what we experience is with the power management active, in which case, another dead end, lol.
One would expect to see no difference in Detail in case of the low-pixel 6D with different lenses, but see more details in the high-pixel 70D in case of the new 85mm lens stopped down.
Would be lovely if Canon just had to say - "eject your CFExpress and continue with a new card"..... but I wouldn't bet on it.... I think there is definitely that scenario possible, CF overheats before everything else, but I think a swap may give you a bit more time, not considerable / unlimited.This brings up the interesting possibility that what we are seeing is NOT actually the camera overheating...but rather the card throttling back when it overheats, to a point where the camera can no longer write to it fast enough for the mode it's in. The camera then has no choice but to terminate 8K/4KHQ/4K120. However, since the card is still able to support lower data rates, you can take pictures and shoot 1080p/4K normal quality all day.

Good news indeed. Do you have an estimated time on the fix availability? Thank you.
Did they say anything about those that have a R5 now?I have a relative that works for Canon an he got info on it too. Said the fix will be before the R6 starts to ship out. So all R5 units on the next shipment will already have it. And all R6 units will have a similar fix already there.
