If you look at my comment history regarding R5 and R6, you will see this is not the case. This was a huge disappointment for me! I've been saving since Oct 2019 to completely overhaul my gear, which is currently APS-C camera and lenses. I have $5700 thus far put aside for what was to be an R6 and an RP, with some lenses. But the R6 overheating issue is a no go for me. I shoot multiple types of scenarios, weddings, interviews, product shots and YouTuber content. One of them being makeup artist who do tutorials, they can't pause while they are working on a face because a camera is overheating.
Fair enough, my apologies then, I interpret a lot of these comments as just bashing away at the new offerings but it is clear you are disappointed in what you wanted the product to be just as I am excited in what it seems to be. A lot of the criticism and noise surrounding these releases seems to be that people think the R5 and R6 are video work horses. Maybe this is exactly why Canon allegedly held back features before- because people are not prepared to be told a product has usage limitations.
Your use cases are clear cases of needing longer filming time, but do you really need the high frame rates or HQ modes or are they nice to have only? What resolution and frame rate do you have now? Even if you do need high frame rate 4K with unlimited times, it is going to use a lot of expensive memory and computer power, and a video camera designed for that specific application is going to suit you better, I should think.
There is a reason that competitors are charging 4 thousand dollars for lower resolution bodies that are not as weather sealed and are designed for video with stills more as an afterthought. Good IBIS, large MP sensors and high bit rates, weather sealing, etc. will all be detrimental to heat generation while lower MP sensors can be read out faster and with less heat and rolling shutter and so lend themselves to extended video work. It just seems like people wanted unrealistic performance out of the new Canon bodies for a very low price, or are wanting the wrong tools for the job. To me it seems obvious these Canon bodies are intended to be the mirrorless follow up to the 6D2 and 5D4 photography cameras that had some video capability- same prices and general features as before too. They were designed for shorter video work at the higher data rates and the designers placed emphasis on being stills biased hybrid cameras, not video cameras.
In the end, why be frustrated about a thing you haven't even bought, hasn't even made it to regular customers yet, etc; specially if you are not already into a lot of expensive EF glass you plan to keep? You could pick any product on the market, and there are many. All of these brands offer amazing tools at multiple price points and one is sure to match your needs. I just don't see getting upset beyond picking the best thing available that suits your usage needs and that you can afford and then doing your best with it.
For what it is worth, people said the 5D4 was a flop for video and yet I've shot some very nice lens stabilized 4K on mine with the massive crop factor and large codec not causing too many problems. I've shot some gorgeous 4K on my Sony NXCAM too. Each is better at some things and worse at some. Same with GoPros and drones. Every piece of gear has an intended use, makes some compromises while excelling in key areas. All just tools with capabilities and an application.
