While FF sensors are great, S35 will remain the professional standard for the foreseeable future. Why? Because the image circle of PL cine lenses can cover S35 but not FF 35mm. That is why professional cameras such as the Arri Alexa, which cost $70K+, still use S35 sensors.
 
 

If you think that Panasonic will abandon the M43 format for the GH5 then you are crazy. Not gonna happen. I will live stream my seppuku on EOSHD if that happens. What will happen is that Panasonic will eventually introduce their newly developed "organic" sensor tech into the GH camera line. This will give them performance better than the current generation of full-frame cameras but in the small M43 form factor. I'd guess 2017 or later.
As for 6K, why? There is approximately zero demand for 6K and it's technically unfeasable for any number of reasons. A more reasonable step would be for for Panasonic to have the GH5 record 10-bit 4:2:2 4K internally, but even that would be beyond the capability of the SD card format for reasonably low compression.

@k-robert Don't worry, Panasonic will not move away from M43 for it's still camera line (and that is what the GH series is). I wouldn't be surprised to see them release a -$10k S35 camcorder though...
As far as your desire for more DR and better low light capability, there will be incremental improvements but a M43 camera will never match the performance of a FF camera (all other factors being equal). It's simply a matter of physics- the FF sensor just has more surface are to collect photons than a M43 sensor does. I wouldn't expect A7S ii performance from a M43 camera anytime soon. Maybe when the "organic" sensor is released...

If there's anything else you guys want to see let me know.

The auto variable ND is the one feature of this camera that seems to live up to the hype, it is killer and I use it all the time. On the other hand, with S-Log having a base ISO of 3200, it's almost required. 
Also, when I compared the FS5 to the RX10ii, I was referring to the basic image pipeline. Both cameras have almost identical bit rates, frame rates, resolutions and were released within a similar time frame. I wouldn't be surprised if they used the same processing hardware. Yes, the RX10ii uses XAVC-S and not XAVC-L but the technical differences between them are few, mainly a different wrapper (mp4) and higher compression with S. and both use a LongGOP compression scheme. Basically, XAVC-S is just a crippled version of XAVC-L. 
As far as the FS5 goes, the good news is that Sony seems to have included a 150mbps bit rate for 8-bit 4:2:2 UHD in the LongGOP standard, so it's possible that it's just a matter of turning it on in firmware. Also, according to a year old paper, they have two more LongGOP UHD modes to be implemented in the "future". Specifically, 140mbps and 200mbps for 10-bit 4:2:2 UHD.
