So glad to see how proud you are of your theory! Of course, since none of us work for Canon, we have no proof that your theory is impossible. How lucky you must feel that this is so!All I said was that folks are acting as if it's an impossible theory, NOT that it doesn't require effort. Having worked in project management for well over a decade I fully understand the life cycle of things and what it takes to change something at the development stage, but that doesn't make it impossible, especially if it's determined that the level of work and cost is warranted. It's just funny to me that people are so adamant what Canon is and isn't doing when the reality is, not a single one of us knows what Canon did, no matter how far-fetched or labor intensive it may have been. Just because people think it doesn't make sense certainly doesn't mean it didn't happen. That's my only point, and unless you work for Canon and know exactly what went on, you can't refute that point.
All that aside, I am glad that your theory is almost certainly - but not provably - wrong. Since the release cycle for their 1 series cameras has been every 4 years, and released in time for the summer Olympics, if this was going to be the R1, then it would mean that they were rushing out their latest 1 series camera (plus, almost certainly ensuring lower sales, since the 1DX III was released less than 2 years ago). I don't care about sales, of course, but just pointing out another reason why your theory is most likely totally invalid. But, personally, I would rather Canon stick to the statements they have made indicating that they are not going to rush out a "flagship" camera, but will ensure that they have every issue and innovation worked out to the best of their ability. I think long time Canon owners do not want to see Canon take on the Sony philosophy of releasing cameras in what many folks considered "beta"versions. I'm not sure they would have the patience, or the gullibility, of those early Sony adapters who bought the first 2 generations of the A7 series cameras. As a Canon user for over 25 years, I would have been really pissed if Canon released such sub-par cameras with the thought that I can just buy the next version, which will fix all those issues...at full price, of course. I did own, for a brief time, the A7 and the A7 II, so I speak with at least my own experience about these cameras. Luckily I was able to see their deficiencies within the return window timeframe and did not lose any money. One could argue that the entire FF Sony A series was a Beta version, as many claim that the camera was originally designed to be APS-C and then changed at the last minute to FF. So I guess last minute changes are possible!
But for a "flagship" camera that will have a heavy price tag, I hope Canon takes their time to get things right. I think, as others have pointed out, that the R3 is a way to go part way there on the way to what they hope to accomplish with the R1.
