I really wish Canon would have showcased the photo and video it could do well... with a little blurb on it can also do extended 4k HQ & 8K in limited situations... instead of touting the 8k off the bat. Now kudos to Canon for not hiding the overheat... but come on... don't get everyone's hopes up and then dash it later w/ an 'oh by the way'. Of course everyone is now going to dig on the negative (pretty much how news works now days).
Myself, I like to know what it will do before going in. However I've accepted that the IBIS, AF, and unlimited full frame 4k more than makes up for the extended video recording modes that come with caveats. Unless someone comes up that 'normal' usage (for me) is compromised with the overheat, it's just beating a dead horse. So far I have not heard anyone having issues with the modes that Canon say are not limited.
Also, for the record, Canon chose the worst terms to use for the YT's out there... 'Overheat' vs 'Thermal Protection'. In computer terms, the first is bad and causes damage if done repeatedly, the latter isn't... it's shutting down before damage can be done. I have to assume the latter term is technically more correct (I can't see engineers running the camera to the point of damage occurring).
