A while ago, photowebexpo.ru posted an interview with Canon regarding the R3 and one questioned asked was "What cameras does the EOS R3 compete with on the market?" I have copied the English translation below. Based on this information I believe the EOS R3 will be >=45 MP and have 8K video. If it does not have 8K video how does it compete with Nikon Z9 which has 8K video? Canon states that the Nikon Z9 is the closest competing model.

What cameras will the Canon EOS R3 compete with on the market?
Of course, the closest competing model will be the
Nikon Z9 , which we do not know much about yet, as the camera has just been announced and has not yet been officially unveiled. What this model will be in reality, only time and reviews will show. Canon's culture is built on respect for other manufacturers, and we always maintain a competitive marketplace that drives the advancement and emergence of new technologies for photographers. But when the Nikon D6 came out, in my opinion, it turned out to be very close to the Nikon D5. So I expect the Nikon Z9 to be a really strong and innovative camera for Nikon.
And of course,
Sony a1because there are cool technologies there: fast shooting, no blackout. However, she just came out, so there is not much real filming and combat experience on her. And for cameras of this level, it will be important to evaluate the operating experience after some time. In other words, our camera will be in the segment of those cameras that are currently announced by competitors as top-end.
