With all due respect but it seems that CR has been swinging and missing a lot lately.
I don't think it is CR guy who is "swinging and missing" lately. I believe Canon is doing a really good job of keeping everybody to shut up. In addition, I believe in 2019/ 2020 let the "road map" slip on purpose to CR and other forums. That way, people "kind of knew" what to expect without being able to hold Canon accountable. By not publishing an official road map, they were/ are able to decide up to the start of production which way they'd like to go with a lens. For example: The rumor mill suggested the RF version and follow-up of the EF 100-400mm L "will have a greater range." Suddenly, patents of a 70-400mm surfaced but Canon managed to surprise us with the magnificent RF 100-500mm. Also, they had more surprises up their sleeves such as the dual-fisheye RF5.2mm
In 2023, Canon is in a position of not needing to let people know what's coming because there are plenty of options already. Just look the UWA options... 16mm, 14-35mm, 15-30mm, 15.35mm, 24mm, 35mm and not mentioning all the great EF glass. I'm pretty sure Canon has raised the fines for breaking the confidentiality clause for those photographers/ YouTubers who get sneak peaks of new gear.
The result being: none of the rumor sites has a trustworthy info ahead of time now.
