R6 will overheat in 4K60p after 30-40mn & in 4K30p after 40-50mn (depending on FF/S35 modes).
Shouldn't be any overheating issues in 4K24p/25p.
Let's just remember we're talking FF no crop oversampled 4K60p with DPAF in 10-bit 4:2:2 internal.
In comparison, the only hybrid camera on the market that can get close to that is the almost twice more expensive S1H which can only do 4K60p with a S35 crop in 10-bit 4:2:0 longGOP and poor contrast AF... and that camera has active cooling on board!

@ade towell There are two ways of looking at this, glass half-empty or half-full. Andrew made a good post about this: https://www.eoshd.com/8k/a-closer-look-at-the-canon-eos-r5-lower-quality-4k-mode-to-avoid-thermal-cut-off/
R5/R6 can be used without overheating issues. If you want maximum performance (which no other hybrid camera can currently give you) well you are prone to thermal cut off limits and high RS. I think it's a fair trade-off situation and Canon are being open about it as opposed to Sony.
Concerning the R6 4K crop, it is of x1.07. It apparently takes a 4K DCI image and truncates it to UHD. No biggie.
As for the S1H being a better hybrid video camera, that is subjective. The poor AF and weight (1Kg vs 680g) makes it a no go for me personally and if you want FF no crop 4K60p in 10-bit.. only R5/R6 will give you that. But of course YMMV.
 

The Canon EOS R5 works in mysterious ways.
Canon chose to implement 8K and 4K/120p on this camera knowing that heat build-up will make for some short recording times. This was a risk, because the perceived hit to reliability can generate a lot of bad publicity. What was Canon thinking and what else does the camera offer for when more reliable recording is needed?

It does all that and then some.
Pixel shift has new options allowing bokeh defocussing etc

On R6 4K60p will overheat (30-35mn) as well as 4K30p (40-50mn) which I personally find are decent recording times for those particular modes.
I never do long shots on high frame rate modes and if you’re doing long interviews, concerts or weddings you should have a second body or cine cam anyways. 
Otherwise just stick to 4K24p/25p for those long recordings and don’t worry about overheating issues.
 
I think the whole overheating topic is overblown but of course let’s wait for some real life testing to find out more info about it.

My thoughts:
 I don’t really get how people are upset that 8k raw overheats...why are you looking at a small mirrorless camera if you need long captures of 8k raw to begin with? Buy a real cinema camera. I think everyone is forgetting what this camera is and what was asked of Canon. Everybody is getting mad at canon for giving us what the majority of people asked.
 
People wanted a canon mirrorless camera that was full frame with amazing IBIS, dual pixel autofocus, high megapixel count for photos , and could shoot 4K 4:2:2 10 bit uncropped, with a swivel screen. So, they did that. They did exactly that and more. So then they thought, well we could give them a full raw 8k readout of the sensor and have them record as long as they can before it overheats, better than holding it back. Also, we can throw them 4K 120 as well and also have them go as long as they can before we max out. I mean, might as well give them everything the camera can do, instead of just not unlocking it and having the magic lantern folks do it for us, right? 
 
So they threw in some crazy bonuses nobody was asking for and here we are, people bitching. The camera everyone wanted is here. The full frame autofocus beast with great IBIS, 10 bit, no crop, and great at photos true hybrid by canon is here and we are upset. Are we complaining that they have the overheating numbers written down? Because there is no way It’s a shock that 4K 60p 4:2:2 10 bit with dual pixel autofocus will overheat near the 40 minute mark...or are we surprised that 8k raw in a mirrorless full frame with IBIS engaged, dual pixel autofocus,  and no crop in a small mirrorless overheats? I mean, what are we mad about here? 
This is the camera that everyone wanted. There are several frame rates and resolutions that Canon threw in that will be very useful within the limits of this specific camera and yes they have limits, but at least they are unlocked and not behind a magic lantern hack like the old 5D. As someone that shoots an equal mix of photography and video, this is a dream camera. I get a high megapixel camera and high quality video, with all of canons special sauce including their great autofocus and colors. I see no mention of limits for standard 4K 24p and 35 minutes of continuous 4K 60 is more than what I need. If it’s not for you, than that’s fine - keep waiting. 
 
There is so much negativity in the world right now, that I’m honestly not surprised that Canon finally doing something good gets shit on. I expect nothing less at this point. 

The R5 will only overheat in 8K, 4K60p & 4K HQ. 
It shouldn't have any problems in regular 4K24p/30p.
Calling it unusable is a little extreme. What other hybrid camera can even approach these specs? 8K/4K120p FF no crop, DPAF2, RAW, 10-bit 4:2:2 internal.
Besides we've had 30mn recording limits for years due to EU laws. Hardly an issue for me personally..
That said, if Sony can do better, bring it on!

Yeah but the Sony's are 8-bit XAVC non-4K60 UHD cams, A9 doesn't even have log, pixel binning cams have other issues. Always some type of compromise with FF it seems..
 

32ms RS is definitely not a good number on a +$6K action/sports oriented camera!
But it does looks like 4K RS is always on the high end (i.e +24ms) on all these hybrid FF cams.
I guess this is an area where APS-C / Super35 still dominates (A6xxx series excluded!).

About the redesign, Tanaka said this at last year's CP+: 
"Many people have enjoyed the a7S II as a video camera, but originally we designed it for stills photography users. So if we’re going to create products [specifically] for video shooters, we’ll have to modify them in the future. (...) The basic expectation is for things like 4K/60, 10-bit 4:2:2, and a lot of manufacturers are doing that right now, but I want to think in a different way and create something that goes beyond the expectations of our customers. "
I'm assuming that in order to get 4K60p / 10-bit 4:2:2 Sony has to redesign the physics of the A7 body to avoid overheating. This physical redesign is why it took them so long to release this camera and also the reason why even the latest gen Alpha bodies are still capping at 4K30 8-bit.
Really hoping the "beyond customers expectations" means some innovative tech like the Vari-ND from the FS line.. that would certainly tip the scale in the upcoming R5/R6 battle.

Personally, my interest for 1DX3 completely died down after R5 was rumoured  shortly after.
As for GFX100 vs 1DX3 vs XT4.. well 3 different sensor size cameras at 3 completely different budgets.
Again personally, above the $6K line I'd rather be looking at dedicated cine cams.. especially if RS, NDs, XLR etc are of importance to you.
XT4 definitely seems like best bang for buck at the moment, kinda like the new GH5.
But if you're into FF (even if just for stills) you still may wanna invest in another hybrid system.

On  tracking/panning fast object at 1/50 24fps you will not see rolling shutter because the motion blur will hide the RS issue. I track mtb at  (200-400 +1.4) 560mm and I have zero problem with RS. Is really unstable platform or back and forth movements that shows up. I have more problem on a horse show jumping parkour as you move back and forth and  the obstacles as they are vertical they tend to be bended....
Btw I did cover the 24h of Nürburgring for teams multiple years so I'm familiar with motorsport.

By the way, sorry for the clickbait title but perhaps a sign towards what is to come in the next Alpha instalment?
First time in a while (or ever period?) that Sony is placing pro CineAlta features in a consumer product!

55Mbps bitrate seriously?! Lmao.. cripple hammer now belongs to Sony. SMH
Maybe not a good sign after all 😕

DPreview has a sample gallery up: https://***URL removed***/samples/5031669290/sony-xperia-1-mark-ii-sample-gallery

Lotta NR at higher ISOs but overall nice from iPhone user perspective. it's got that Zeiss look.
