...in a different thread, I wrote this:
What I like about the M6 II (so far) as far as ergonomics are concerned:
(1) In my hands, the ISO was too easily accidentally changed in the M6 I. It looks like this has been changed.
(2) In my hands, in certain specific usage patterns (i.e. dangling around my neck with a non-stock [much-smaller] strap...while mated to te 18-150 lens), the camera was able to turn itself on. There are threads on this at a couple of places on the 'net. It looks like this has been changed, too.
(3) It looks like the focus position, when the viewfinder is attached, is more like the m5 in that you can move it around on the touchscreen with your fingers
I will buy at least one.

adding:
(4) examining the video a bit more, the ergonomics, for me, are also improved in that exposure compensation is more like the M2 (and the S90 and S95) than the M6. A big win, for me.
