The 4k HQ mode on the Canon overheats. You can get the same thing by shooting 8k on the Sony, which if it does not overheat will be a large benefit.
The non-HQ mode on the Canon is perfectly good. Do you want to know how I know this? Because it looks barely distinguishable from the a7sIII.
The probability of you ever being limited in video by this camera seems unlikely. But sure, I'm sure some people will still upgrade for such minor improvements.
If it is limited to 30 minutes that means that the A1 also overheats. But of course it has the same passive cooling as the A7SIII for way more data, so no surprise there.
4K HQ is the mode I've used on the R5 all the time and so far it didn't overheat, it didn't even bring the temperature warning sign on. It did go down to 10 minutes, but after a short brake I get the same amount back, so after 10 minute shutdown I am back at 20 minutes. Perfectly usable for me, maybe in the hot summer I need to be more cautious, but I can shoot in standard 4K if I need to.
I really don't want to shoot 8K, totally unnecessary for me, but I don't see the benefit of paying this amount of money to be forced to shoot in this mode. I mean, it is a very high-end stills camera but the video is not quite at that A7SIII level.

I don't get the bellyaching about $2K more than the A92. The people who this camera is aimed at own $10-30K in glass for photographing birds, wildlife, sports etc.

I used to buy 1DX and 1DXII so I'm sort of used to this type of price. Of course I used to get CPS discount on those bodies. The A1 will end up being the most expensive camera I've ever bought at $8500 CAD. The 1DXII was "only" $6800 CAD. I had left Canon before 1DXIII so never got to spend a cool $9K on that one.

If I was a lot richer I'd buy it for the EVF res and mag.; the lossless compression, the five axis stabilisation on adapted glass and a few other little things. I'm not so I won't.
But if I was a birder (and maybe when I retire in around a decade I will be) I'd be talking to my bank now...

Is it confirmed already? I mean sensor readout is faster in A1 so how would R5 achieve better IQ in FF 4K video?
The sensor readout is not the same in stills mode as in video mode, you can see even the A9 and A9II have some rolling shutter in video mode.
It is down to the internal processing: the Digic X in the Canon can handle the downscaling (somewhat, it of course will overheat at some point), while on the Sony with their codec implementation this would produce a lot of heat, so they've just decided to skip it instead of getting it to overheat quickly.
I mean, some say it's a small thing, but considering the price, I don't think so and it is just a way of not getting into this overheating drama. It is the same with RAW output, they advertise this feature but it is line-skipped just like on the Z6 series e.g. not "real" RAW like on the Canon cameras.
It just means that it won't be able to match the A7SIII in video mode regarding noise and dynamic range despite costing almost double the price. I am sure A9II users will not complain considering what they've had in the past regarding video. But if they advertise this camera as "totally unlimited in every way for photo and video" then they are not quite telling the truth.

One thing that has occurred to me recently, as we cram ever more powerful processing into tiny mirrorless bodies, is what sort of longevity these bodies will have considering the amount of electronics-killing heat generated internally over their lifetime, especially when shooting video. In the past we've worried about mechanical shutter lifespan. Do we now need to start worrying more about circuit board lifespan or sensor lifespan?
it's gotten complicated with modern technology, but in general there is still no comparison between mechanical vs. solid state lifespans, the latter wins easily.
in part because even the alpha 1 probably still doesn't have cutting-edge node sizes like you'd see in a smartphone, there isn't enough demand to justify the cost.
intel failed to deliver 7nm with decent yield, they claimed 2023 as the delivery date... amd/tsmc is doing much better, but none of that is cmos sensors or cpu chips that we'd see in a camera.
in other words, solid state component lifespans in cameras won't be an issue.

Positioning the A1 in the Canon 1DX III market makes a lot of sense given their technological moat of the stacked sensor. Strange that they didn't take this opportunity to also create a larger pro body as well. In addition to better ergonomics it would greatly improve the thermals. The target market of the A1 will be lugging around bags of heavy glass so shaving off a little bit of volume on the body makes no sense.

3-4 stops is a shutter speed 8 to 16 times slower shutter speed than the Sony.
1 stop would be noticeable, you don't need 3-4 stops to be noticeable.
Well, the actual improvement in rating is not 3-4 stops. It's up to 5.5 stops with Sony a7s III and up to 7.5 stops with Canon R5. That is a maximum of 2 stops, which is 4 times slower shutter speed. I would say that a 2 stop improvement is about what you would expect in moving from a Sony camera to the R5. If the Sony camera was the a7c, based on what I've seen about that cameras poor IBIS implementation relative to Sony's own cameras, I think you would maybe actually see a 3-4 stop improvement.

the alpha 1 uses bionz xr chipset, it has 8x more processing power, so where is it stated that the alpha 1 has the same rolling shutter measurements in both stills and video?

i can't make any sense out of that.

there is no such thing as "real" raw video, like we know it for stills, the best raw video compression that i've heard of is still something like 3:1 compression... the r5 is at least 5:1 compression, and it has weak p.q. with overheating in some 4k modes.

where did you see sony claim "totally unlimited"? post the specific link.

Based on my experience this will not be an issue at all.

As I am getting ready for an affordable upgrade this year after several years of minimum photographic activities; I've been reviewing my past shots in three major areas of my photographic interest (BIF/birding, flowers and insect macros) to see where I should center my cheapest upgrade. I just finished processing one old macro capture (below) from P&S zoom 13 years ago when I finally had the time to digest most of the recent news on the A1. Can't help but drool on the listed specs.
I've been expecting a curved ball (not a sensor though) to be thrown by Sony but not at that price. I've conditioned my wife for up to $5K only for possible purchase this year. More than that would be a tough sell.
The just processed image above (many more to process) from a 7MP P&S of long ago seems to indicate I am quite there with usable/quite ok insect macro. Just need to improve on some areas like diffused on-board flash and exploring stacking. Ordered an old Panasonic FZ80 to play with focus stacking. The small sensor size would take care for the needed DOF. With flower shots, my APS-C gears with my old but still ok AF and manual lenses should still be applicable and enjoyable.
Upgrade path then would be on the BIF/birding and the A1 and the A9/A9II would really fit that need. With the announced A1 price as is, only seeing the 4 year old A9 plus the 200-600mm as the most logical wife-approved upgrade (also contingent to the targeted S1.4K added stimulus payment).
I've been quite loyal to Sony even when laughter and belittlement greeted their entry into the DLSR world. Used/bought their A100, A550, A55, A700, A77, A77II, A850, A900, NEXF3, A6000, A6300 and A6400. As I need only the improved AF performance, I hope there would be an affordable A9/A9II-like APS-C or FF bodies in the current roadmap.
Sony before was that fly underneath and now the one on the top, how time "flies" :-).

sony already improved the cooling design with the a7siii, it's far superior to what canon did with the r5/r6 fiasco.
and given how primitive canon sensors are, i.e. no bsi and no stacked sensors, i suspect that sony is using chips that are more power efficient than what canon uses, so a bigger body isn't necessarily going to give better cooling, unless a fan is used.
as i recall it, sony stated that there aren't any sensor cooling sinks with ibis.

I’d wager it has more to do with controlling costs and reusing bits and bobs from other chassis. But you’re right, a slightly taller grip would have been welcomed by many.
