Unfortunately, I think Sony closed the Cyber-shot division in early 2019, when it decided that phones were the future for consumer cameras. Consequently, there have been no new or updated Cyber-shot models since July 2019.
There's is a technical argument for developing an RX10M5, but maybe there's no-one left to do it? All the former Cyber-shot staff left the company, or transferred to other departments.
Instead, there's a new department that canibalises other Sony cameras to make ZV cameras for vloggers. They, apparently, are the only compact cameras that still sell.
Are they actually selling or they want to give this impression by repeating the same thing over and over until it is taken as fact?
I watch YT and there is no one vlogging with those cameras, expect the people that keep doing tutorials for those cameras. No one using them as studio cameras for their YT videos. Most people are asked what gear they have, many do a video just to show that, literally showing their gear, etc, but as real life video content creators that does not include talking about gear and reviewing gear as sole occupation on their channel.
So again just a handful of people who only speak of those cameras in all their videos, no one is claiming to use those cameras that actually vlog and not preach about those cameras.
On IG is pretty much Iphone and smartphone galore, there are dozens of great account from garden designers to farmers, to architects, it's no tiny 1" Sony camera. I doubt people who post cats all day long buy the Sony 1" cameras.
