Absolutely my thoughts.  This camera will sort the men from the boys.  I've seen footage that could go head to head with ARRI and Ursa as you say, but I've also seen footage that has more of a video look than a 8 year old apsc cannon dslr (way more infact).    The correct settings and grading will make all the difference.  And obviously the quality of the cinematography also.  One thing about a lower price point is that it makes it more accessible to more amateurs, so the lower average quality of craftmanship might make the camera seem worse than it would do otherwise compared to more expensive cameras.

The vast majority of hobbyists and vloggers will get better results with a GH5/S or XT-3 than the 4K Pocket. Just like the vast majority of them got better results with a GH3, 5D3 etc than the original Pocket and the endless ‘organic retro lut’ grades that abounded with that camera. Although Blackmagic are trying to aim this camera at a broader market that the Ursa 4.6k/Pro, I don’t think it is the right solution for people who don’t use Davinci in their workflow.
BM have tried to simplify things for users with the Gen4 colour science but they overestimate the average person’s interest in correctly white balancing (even in post), using more than one node, appropriate lift/gamma/gain and selective sharpening etc. The fact that this camera has a much higher quality ceiling than everything else under $3k doesn’t mean it will play out that way in most situations.
It is in that tricky space between being able to cut seamlessly with an ARRI or Ursa Mini Pro(which looks fantastic with Gen4 colour) and looking potentially worse than consumer cams.

After having some time to digest and looking at some footage…
I know it goes against the way they’re marketing it, but the GH5s seems more suited to events and weddings where you don’t have much light control, whereas the GH5 is for more fast paced commercial work where you do (and use manual glass where gimbal work is a nightmare). I see no image quality improvements outside of low light, and I see several downgrades in terms of versatility in what modern producers expect from a stills form factor cam. 
I honestly like that Panasonic have released it, but I think that it should cost a bit LESS than the GH5 if anything…even with the free v-log. 
And despite some hyperbolic comments here, there is no way either camera is comparable to the EVA. In a high end workflow, they are just two different types of b-cam.

When a GH5 + Zeiss + IBIS can get you this, I don't see a GH5s as an 'upgrade'...unless you're doing weddings or events without lights:
 

Based on what I have seen, rather than the marketing materials, I regard the GH5S as a great cam for event and wedding shooters who are always running around with monopods, little gimbals and little lenses. However, in my workflow, I don't want a b-cam that doesn't have IBIS. I have enough heavy gear and manual glass to deal with without the headaches of a rig for a stills body cam.
Whether the image quality is an improvement over the GH5 outside of low light, or actually a little worse...remains to be seen.
In terms of what is good for low budget cinematographers, I suppose if the highlight roll off is as good as is claimed and the motion cadence is improved...the GH5S may be a contender over blackmagic purely for ease of use and reliability.
I definitely don't think that the GH5S release is a 'fail' in any way. It has it's place and people on forums have been loving the whole 'low light monster' meme since the A7S came out. I want Panasonic to continue to innovate.

Well I could, however I think I'l be reaching to the original GH5 for IBIS - I actually own ZERO I.S lenses! (one of my fave's being the Olympus 40-150mm 2.8). One of the reasons I dumped the FS5 is because some of my shots from 50mm had an annoying ugly-style handheld jitter here and there, regardless of my steady hand. So IBIS happened. 
Having a GH5S would fill a gap (lowlight), although most of my shoots are controlled. Another body would really be for multi-cam reasons. 
Great lowlight is a bonus, however the main pull of the GH5S is the better quality image via much smoother looking highlight rolloff. Its awesome what they've done. 
As it stands, in the most logical non-emotive sense, I think a 2nd GH5 body would be a better fit.
