There are now the first wild rumors (meaning they are unconfirmed and not from reliable sources) that Canon will announce the new R1X in 2025. I think this is more like wishful thinking after the great disappointment of the R1. Canon clearly stated that the R1 was the ultimate flagship. However, I bet Canon will learn its lesson and perhaps announce a high-resolution flagship in 2-3 years. But before that we will get a new Sony A1II and a new Nikon Z9II that will raise the bar further.
