Depends. Do you need the video production tools that are possible on the GH4? Like V-LOG L, anamorphic mode, headphone jack, TC, etc? If not per se, the new G80/85 has newer sensor tech and like the G7 and GX80 already, have a much cleaner image with a little nicer colors. On top of that it adds the 5-axis body image stabilizer which shifts the sensor to allow all of your non-stabilized third party lenses and primes to finally have stabilization! That's a major deal!
Again. Depends. Every camera has their own strong points. The GX80/85 is nice 'n small. But with the G80/85 you would gain a vari-angle screen, instead of a tilty one. You get a mic-in, which sorta is a big deal if you want to record audio internally. Features Cinelike profiles. And it has weather sealing and is grippier.
I'd say the best option for the time is the G80/85. It's the new Panasonic hybrid flagship for stills and video. Just to have the GH5 beat it, but at double the price, half a year later.
-- if you're residing in the UK/EU, check out the killer deal I posted in the main thread:

The GX85 does not have mic input, and the battery is smaller. The body is smaller which is good for vacation, but shape is worse for work.

Thanks! Hercules is great for product shoots but it's a little fiddly to control as it only has one button and many settings. Would love it if they made an updated version with smartphone control. Some of the shots are also a bit wobbly and I'm not sure why, could be the IBIS though.
If you're going to use the rail on a tripod it needs to be a steady one. Didn't work well with the gorilla pod, I used a Benro alu tripod . Small primes like PL 15mm and 25mm on the GX85 works very well with Hercules. It can tip over with bigger/ longer lenses so be careful. 
Haven't shot so much at night yet, but it holds really well up to 1600 ISO and pretty good at 3200. Did you see the ISO video I posted in this topic? 

Or @jase festival video? 
 

Interesting. Thanks!

I just finished another shooting day on my BMPCC and SLR Magic set, and I'm still so in love with that kit. It renders very 3D, flares beautifully, produces great skintones, does lovely things to highlights, and has rock solid build/handling.

I'd like to give the Voigts a proper workout, but I've been happy enough with my current setup to avoid the temptation of yet more glass.

...for now.

Might not have a big boy sensor... but if it's able to play its cards right... this could be the ultimate camera! I honestly can't find much to fault it on. All comes down to... will it keep up in the video department? Or will it be riddled with stuff like moiré and compression artifacts?

Thanks man, that means a lot! 
Hehe, I don't know about lessons but I can tell how I grade with Color Finale. I'm still learning too. I guess you have you seen Denver's tutorials?
I didn't use any LUT as I was going for a natural look and I think most LUT's are too stylized. Some LUT's can be good for a base grade though. 
I used Standard 0, -5, -5, 0 with WB set to Sunny, which was to blue for my taste. I didn't set A3G3 as in my test it made a white wall yellow. I have to test more in different settings, but for now I prefer to fine tune WB in post. Most shots were f/1.4 btw.
In Color Finale I first add Color Wheels and adjust exposure looking at the RGB parade. Then I add another Color Wheels and set saturation, in this case 1,1. Mostly I raise it between 1,0 and 1,1 or don't touch it at all, and a few rare times I lower it a bit. Then I add a third Color Wheels and adjust gain to set WB, which is a little tricky as you probably know. Usually it is enough to adjust the gain, but sometimes I also adjust gamma and lift, although not in this video. The last thing I did was to add Curves and pull down the shadows in the blue channel. This really helped getting that warm feeling. 
So basically I adjust exposure and WB using 3 x Color Wheels, and fine tune with curves and vectors if needed. The reason I use 3 Color Wheels is to see what every little adjustment does so It's easier to go back and forth. 
Here's before and after:

It's a fantastic image for the price! Prices in Norway: GX85 is 590 euros, G85 is 1050 euros and A6300 is 1335 euros. If the price keeps dropping I might have to keep it as a B-cam when the GH5 is out, which isn't so bad as it's a perfect match for Hercules with PL 15mm and PL 25mm:

It's not so much sharpness/contrast as it is actual details and most importantly color... as said before, that top down mode looks real good, everything in one plane. Once you start to add depth, things just seem to get messy and that doesn't just have to do with the new lens and AF. And colors are just weird to me. I'd say footage shot with the Phantom 4/Inspire 1+X5/X5R(OSMO) and probably GoPro Karma, might look a little more hyperrealstic/picture perfect and nicer. To me. So of course it's subjective whether you like that kinda thing or not... you might call it 'digital' or whatever. Also, you saw there that it's not quite as smooth as they as well mentioned separately. I mean. Hands down awesome small camera, no doubt. But not sure about praising sub-par image quality in order to justify buying one. But then again 'beauty is in the eye of the beholder' is what they say...

Yeah, that says a lot, doesn't it. Honestly, Albert Fast has been doing great stuff with the G7! And it's an cheap as fuck camera that doesn't overheat! He uploaded this a few days ago:
 

oh just the snippets of 4K that have been posted ( think they're all on this thread).  To my eye it looks a bit more organic than the gx85, but its early days

I bet it will be at least as good, and likely a bit better. Pixel count is but one factor in lowlight performance. 

They're both set to Natural 0, 0, 0, 0. WB 6000 K and the same lens. No color correction. Even with the same settings the GX85 is a little brighter so maybe that have something to do with it? In that video the WB is almost spot on with the GH4, whilst the GX85 is very different although they were both set to 6000 K. 
After making a few comparisons I agree with you that the GH4 has slightly better highlight rolloff and yields a more pleasing image (less contrasty), especially with Cine D and off course V-log. On the other hand when I actually used the cameras it was easier for me to achieve better results with the GX85 due to new color science and noise performance.
If the GH4 sensor wasn't so noisy I wouldn't have sold it as I really liked that camera! When the GH5 finally arrives with the best of both +++ I will upgrade as soon as possible and probably keep that camera for years to come.

Better or worse?

What have you seen?

@Fredrik - Looks as though we've pretty much come to the same conclusion.
@Raafi - Were you starting from Standard or Neutral?

Here are a couple raw shots from my trip/shoot. It's tough to tell how much the settings are doing because it's been very overcast both days I've been here, but the settings I decided on are: contrast: -5, Sharpness: -2, NR: -5, Saturation: -5. The  second shot shows how much contrast the camera is capable of. IBIS looks nice on both (lens is manual with no stabilization):
 

Having mic & headphone jack is still worthwhile for those ultra lowbudget or ultra fast turnaround jobs, or even just simply so you can stick a little shotgun mic on the camera and get better scratch audio for syncing than use the camera's own microphone.

@mercer - Yes, I mean that at least for what I do where an edit can be made up of lots of shots made in very different (usually available) lights, having to regrade everything can be a chore that isn't always justified by the end result. I've got years of experience grading raw photos so I'm quite good at it, but still...
@Fredrik - I had seen that before and it looks very nice indeed to me. My only concern, as you mention yourself, is that your starting point is very flat lighting so I'm not sure it would always be a good strategy in documentary shooting conditions where you will probably encounter greater contrast.

I've also stopped exposing to the right. I don't even use zebras anymore. I have been trying to keep my shots about a stop under using the in camera meter. But I am also shooting horror/thriller genre narrative shorts, so I am probably looking for a darker tone than others and since the shadows stay pretty clean at a stop under, I have been pretty happy with the results... Of course I am going to sell the GX85 pretty soon. Not because of the camera's quality, just because I've decided to invest in Canon glass and utilize DPAF and in my opinion, the more pleasing Canon color science.
However, when the prices drop on the GX85, or maybe even the LX10, I will probably buy back into it, but for now that money can go toward other more pressing equipment. 

Thanks for posting the tests @Fredrik Lyhne. I had actually seen that clip on YouTube when I was researching this camera. I loved the consistent tonal performance on the skin tones all the way up to 3200iso. 
It's funny, when you're researching a camera sometimes it's easier to find tests than it is to find actual finished pieces shot on it. Especially for a newer camera like this one. 
On on my way to the airport now so I'll be sure to post some stuff once the trip's over. The IBIS was the killer app that made me want the camera. Sure,more expensive bodies like the A7rii have IBIS, but then you've got to deal with the Sony look, and it's almost 4x more expensive. 
Shooting-wise my priority is protecting the highlights so maybe I'll try the adjustment @DPC suggests. 

Noise and resolution look better for sure. I'm not sure about the highlight roll off though. Look at the specular highlight on the marble. The GX85 looks burnt. Maybe it's a more contrasted picture profile?
