Interesting. I posted on the micro four thirds subreddit recently asking if the Panasonic app integration was any better than Olympus' (which ... isn't good) and commenters seemed to agree it was not.
I'll consider a switch to a Panasonic for my next camera, since OM Systems seems mostly moribund.
FWIW I don't know if they'll make another G9x. The most recent similar camera would probably be the G7x Mk III. I think that's probably the camera I'd get if I were to replace my G9x tomorrow. I'm a huge fan of the small size of this G9x though.
I had a Panasonic (GX85) and have since switched to Fujifilm, but I found the menu system UI and phone/app integration on the Panasonic a lot better and more usable than many other cameras I've tried (including Sony's and Fuji). The Fuji (X-T30) makes up for it on the UX front through by exposing more of the settings via external controls.
