I guess there was a sale on tinfoil hats. Hope you got a good deal!
The R3 was intended to be the R3, because Canon didn’t believe mirrorless tech met their criteria for a 1-series body at that time. I posited at the time that it could be as simple as lacking cross-type AF, and gee…now we have an R1 with cross-type AF.
Having said that, Canon recognized that some of their customers wanted a pro-level body able to take advantage of the high-end RF lenses available, e.g., the 28-70/2 and sharp 50mm and 85mm f/1.2 primes. So they released the R3 just a year after the 1D X III, and followed it up with the R1 right on the 4-year 1-series cycle.
The R1 is aimed at 1-series DSLR users, just as the R3 was, so strong similarity is expected. Not sure why this causes confusion…perhaps because people think they know the market better than Canon, or because people think Canon should do what they want just because they want it, or some other ridiculous reason.
