According to DP Review , the R3 will indeed feature a 24 megapixel sensor.

I see many continue to hold out hope, reasoning that it’s possible Cable and other R3 shooters submitting images simply don’t want to shoot anything higher than 24 MP. The flaw with that line of reasoning, however, is that Cable is also shooting with two R5 cameras in his gear bag and is submitting images with higher resolutions than the R3 ones. If the R3 had a higher resolution potential, it would have shown up.

It’s time to admit it and get over your disappointment. The R3 is a 24MP camera.

It also stands to reason that when they're working on a new technology, in this case a BSI CMOS, that they wouldn't instantly have the highest pixel density available. They had to come up with the architecture, the manufacturing tooling and processes, and then prove that it could be mass produced. The only way to do that is to do it. And a proof of concept is great, but making money off of the result is even better. So they get it all figured out on a lower MP sensor, start cranking out sensors, work through all the bugs at a low rate initial production, and slowly ramp up. Then, once all those details are worked out they can work on cramming twice as many pixels in (again, not only BSI but also DPAF, which means they're already doing 48MP on a 24MP output sensor) and get a decent yield.

Hard to believe Canon’s 2021 chip fab capabilities are that far behind Samsung’s from 7 years ago.

How long has Canon had BSI CMOS fabs? How does Canon's CMOS chip architecture transfer to a BSI layout? Did they have to entirely reinvent their technology? Because the issue here is that this is new to Canon, not to the world. Canon had to figure out their own way of doing it....assuming they didn't steal or purchase the tech from someone else.

Presumably they would have licensed pieces of the required IP instead of being more than 7 years behind?

For example, Canon got CMOS engineering advice from Mitsubishi when it set up its sensor fab operation.

Samsung sold cameras in 2014 that had 28 MP APS-C BSI CMOS sensors.

And those 28MP sensors were Dual Pixel with two photodiodes at each pixel location? And while BSI CMOS may define the architecture of a chip to a certain point, there are still architectural details that differ from sensor to sensor.

2014.

2008.

That's the year Sony announced development of their first BSI CMOS sensor.

2014.

That is the year the first BSI showed up in an interchangeable lens camera.  No, it wasn't a Sony nor was it made by Sony.   In fact,  some argue that sensor is still better than one found in the camera Sony released just a few days ago!
