Sony will still sell RX100 cameras as long as there is a demand, however they can't technically outperform the M7 without redesigning the whole thing.
The RX100 VII already does everything a pocket camera can and fast too, there's nowhere to go from here.
Canon did the right thing when designing the V1 or how they call it, but Sony has bigger fish to fry than to design a new compact camera body, the demand is not there anymore.
Cybershot cameras are a thing of the past.
Yes
The Powershot V1 is a vlogger camera, Canon's very belated response to the Sony ZV-1 (notice the similar name?). So, no EVF or flash.
To its credit, Canon has made a much bigger investment in the V1 than Sony did with either ZV-1 model, including even coming up with a new sensor size.
Curiously, this model was announced months before shipments will start, perhaps a sign of Canon's panic that it has missed the boat with the vlogger market, already well catered for by Sony, with at least four separate models, including even a full-frame model.
The Powershot V1 seems to be intended to compete mainly with the more expensive Sony ZV-E10 model rather than the entry-level ZV-1, which has a larger (APS-C) sensor and an interchangeable lens (so any of Sony's vast range of E-mount lenses can be used).
I'm not a vlogger, so I can't assess which of these models is most appealing, and whether late-comer Canon will make any headway against the entrenched Sony. But it's a confirmation that the vlogger niche is the only part of the compact camera market that still shows some life.
Sony spotted that trend many years before the others — so despite what we keep hearing in this thread, Sony seems to be particularly well informed about the market! It was also the first to offer mirrorless APS-C and full-frame cameras, and they share the same lens mount.
