My favourite cameras are GX85 and NX500 and TZ81 (with 30x zoom) - I also have GH4 (no desire for GH5) and others ... all with 4K
GX85 is an excellent camera, EFV, moveable display, 4K (with 25 or 30 fps - like GH4), but best is: it is small, it is tiny!
I do not like big cameras, heavy equipment .. so I have NO G80/85!
I follow your reasoning, but with the selection of high quality compact mirrorless cameras available now, there's really only a tiny bit of market space left for each model. In the compact range, Panasonic alone offers the GM5, GX85 and GX8, adding the GF9 in a few days. In addition, there are compact models from Olympus (Pen F, E-PL8 and E-M10) plus Fuji, Sony, Canon, Nikon and others too. Most of these cameras are very good, and I'm impressed by Panasonic's ability to churn out one quality model after the other. Although they were the first to present a mirrorless camera, they are not in any way the market leader, and their efforts must take a lot of resources.
For me, having the GM5 and the GX8 already, buying a GX85 would be complete nonsense, particularly since it uses a different battery from either of the two I have. It's clearly good, compact, reasonably priced and all that, but I paid less than the price for a new GX85 when I bought my mint GX8 and only half that for a new GM5. That's scary.
I consider the G85, since it offers most of what I need from the GH5 at half the price or less, and it uses the same battery as the GX8, which is great when travelling.
The conclusion from me is that while the GX80/85 is a fine camera, maybe a classic even, it will probably be discontinued or replaced within a year. That's kind of scary for a person who lived with an OM-1 as his main camera for thirty years :shocked:
