Neither is going to happen. The photography market has split into three camps.

Casual users who care about apps will just use their phones and the quality will be on par with Micro-4/3 and likely APS-C with computational photography advances.

Prosumers will stick with smaller full frame optimised for style and old school usability e.g. Leica. Professionals will either use full frame for speed or move towards medium format which Fuji is leading the charge towards.

I've noticed that a bunch of camera brands have started making 'vlogger' cameras targeted towards youtubers and others. The camera I'm describing is pretty much what an 'influence' camera would look like or the next stage of these vlogger cameras. Someone who would benefit from their photos being higher quality and also wants a way to frictionlessly publish them quickly. A Ricoh GR with the features I describe would be the ideal version of this.

I bet we'll see even better cameras in mobile phone sooner or later. iPhone 13 max pro already has a fantastic camera.
