I see it like keg.
After a short trial period with RP I am done with FF and perhaps, even all system cameras, too much expense just for fun.
I am taking pictures for pleasure not for profit and, I must not have the ultimate possible IQ.
The killer argument for the R-system is the lack of any 3rd party lenses in AF without adapter.
Right now I am quite happy with my 1" sensor gear, although the M6 II and its lenses achieve higher IQ.
The biggest issue for me seems to be convenience and ease of use.
This is the reason why I now take my Sony cameras on air travel and leave the Ms behind.
One thing that hits me each time I take out my M bag is, that I am bothered and troubled by lenses choices and changes, something which I enjoyed far more in the past. May be I am getting too old?
Anyway, most likely I will not ever again buy into a new system camera. I would be very happy if Sony brings a successor for the RX10 IV and RX 100 VII within the next years. Until then I may continue to use my M stuff on certain occasions.
Also, I am having a good look at the smartphone market and who knows, in 1 or 2 years, I may buy a top line smartphone that covers wide to moderate tele with good IQ.
Right now I am not completely sold on this, because I see a big limitation in the fact that the SD card expansion to use RAW is not given. YMMV.
