OR wifi sync and phone sharing that doesn't suck. But no camera manufacturer has shown the ability to do that, so an android app mode is the next best thing so they can offload the software writing to much bigger tech companies instead.
Top 1 annoyance with non smartphone cameras is sharing the photos I just took with other people at the event. I'm not fucking around with the frankly awful wifi experience on most cameras and I'm not going to bring a cable or sd card dongle to do so either.
# 2 is the lack of built in GPS. It's 2021, adding GPS is extremely cheap, especially if you've already done wifi anyway.
#3 is qi charging. After a shoot put the camera on the wireless dock and everything is syncing well with the local desktop computer.
My bet is Apple
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.
No, i just want org-mode.
