I have no scientific backup for this but I'm convinced adding grain/dithering also intensifies perceived colour depth. 

I'll give Hybrid 5-axis a go and report back. IMO the GX80's IBIS is pretty good, taking out almost all the micro-jitters, which is what you really want anyway. Does it replace a tripod? No, but I'm sure if you turn off IBIS altogether, you'll notice a huge difference.

The manual is a mess. Panasonic probably gave it to some Japanese kid to translate it for $10, ans he used Google Translate. 
 
There is a video on Vimeo with the eStabilization (with and without), and there is a slight improvement in the already excellent stabilisation. Though it crops in further into the frame, and thus is a curious tradeoff. 

Adding a bit of grain can help dither digital highlights from having razor sharp edge contrast clipping as well as give an overall image the impression of added sharpness without making the edges buzz. When integrating CG elements into live action plates it is still one of the the go-to methods to help get the two to blend together better. An image with grain can still look very clean, as everything is uniformed with the global grain effect....which can be very different from digital 'noise' - which can sometimes only effect the shadows of an image, and is often not as monochromatic as film grain. Denoising an image - then adding grain back in can work great...again, this is often because often the non-uniform colour noise is removed/reduced, then a gentle wash of global monochromatic grain can really unify an image in it apparent sharpness and contrast. Film Convert grain is pretty good, but when I can I use real telecine scans from 35mm and overlay those at varying opacity. It is of course often down to personal taste and how effectively/subtlety it is used.  
I tend to regard image noise from digital as similar to the interference on a badly tuned old analogue TV...can sometimes be very a distracting buzz and detracts from the viewing experience.
Grain is more like the pops and crackles you hear on vinyl...part of the experience and can actually add to the experience when used well - seems to add some impression of physicality (even if emulated digitally). Subtlety is key I think - does not have to be very obvious at all to improve an image (unless you are intentionally going for a grind-house look or trying to emulate old 16mm stock).

Actually Film Grain doesn't have to be very Obvious (for want of a better word). I saw some films (most likely shot on the Alexa and Red Dragon), which looked way too digital, and un-filmlike, without grain.
IMHO grain doesn't make the image worse. It makes it better. It makes it seem more alive. 

Film grain is best when used after denoising an image. Anytime I use Neat Video to reduce noise I'll add a layer of grain. Otherwise it looks like plastic. Noise/grain at low ISO's are fine but when you get up to 1600 it can look nasty.

It is very likely that either Panasonic doesn't include IBIS or has an option to switch it off during recordings. The IBIS has 2 main issues:
1. Heat issues (especially in a weather-sealed 4k camera, and one that does 4-2-2 10-bit Internally); and 
2. Noise: If the GH5 is to have usable sound from a mic mounted on the camera (via a camera plugged into the camera's mic socket), then the IBIS noise may be an issue (unless some shotgun mic can completely isolate the sound from the camera).

Hahahahahahahaha. 
See, even the GH4 seriously outsold Panasonic's expected numbers, and thus production had to be seriously ramped up.
If Canon makes $100 on the C100 in net profits, then probably Panasonic makes $500 on GH4 (these numbers were obviously Very different, initially). But the GH4 probably sold like 50-100 times as much as he C100. So, in the end the pricing isn't governed by anything except net profits.
That is why field monitors cost so much more than Smartphones, despite the kind of features and technology found on each device.
At $2500 the GH5 can make a killing for a 4k 4-2-2 device, if it can attract a certain minimum numbers of people, who will primarily use it for stills. The DSLR/DSLM filmmaking community is still a very small proportion of the DSLR/DSLM buyers, and therefore its photography features would be a huge governing factor for its sales figures. 

I am guessing the price would be more in the ballpark of $2500, if it has 4k 4-2-2, and 5-point IBIS (and most likely a lot more tricks up its sleeve). 
Edit: $2000 not $2500. We shouldn't give Panny any such crazy ideas ;-)

Panasonic is moving closer to sending Canon's 5D Cameras to the grave. 
Niiiiiiiiiiiiiiiiiiiiiiice ... 

I think Dwayne Johnson is going to surprise people in the coming years. When he was first trying to breakout, we saw he was interested in being part of riskier, more art-house productions. And after struggling to be taken seriously (and trudging through the likes of The Tooth Fairy and Escape from Witch Mountain), I'd be willing to bet he's going to use the clout he has now to stretch and participate in some more thoughtful/compelling/cutting edge cinema. I doesn't hurt that he's a genuinely good person too, and deserves his success. I put he and Keanu Reeves in the same category: they've both built up so much goodwill in the industry and with their fans that (despite any perceived limit on their acting chops) that they are bulletproof to critics.

Do you know about photographers... aka still shooters? ?
Anyway... buzzing for the gh5.... seems absolutely perfect for my needs... bring it on.

I think it's terrible if their quality control is not too good. And could be worse if they don't have great customer service either. 

Love it.  FT4 rating...  That's like changing your relationship status on FB, so you know it's legit.  No crop in 4K.

Why would it? If you think about it, 10-bit means less compression than 8-bit, sure the bit rate is higher but I don't think there would be any overheating issue, even more if you consider that the GH4 is the coolest 4K camera out there. Processing is more important than bit rate, H.265 might be more processing intensive if they choose it, but 8-bit or 10-bit shouldn't change much.
Sony's issue is not just processing, it's the form factor. The NEX cameras overheated in 1080p! I had two of them and they both had overheating issue, the form factor is simply too small, Sony knows it, they just choose to ignore that and preserve the claim of the smallest and most compact FF cameras. Bottom line, there is nothing really that would indicate that it would be just 1080p because of overheating.

Way too expensive for a fully manual "slider".
I'd also be weary of Edelkrone. I've owned the SliderPlus, Pro, Action and Wizard. Their products are often flawed, especially when it comes to the tolerance of moving parts (which is critical). 

I noticed that the Video HDR feature on the 5D Mark iv seems like some scam. In regular mode it pushes Dynamic Range in video to that of a smartphone (basically Terrible). And then has an HDR setting to bring it average/ normal levels. From the various Videos and Frame grabs I saw (online), in regular mode video seems to be about 7-8 stops, and in HDR mode maybe 8-9 stops. 
I dunno if it's funny or ludicrous. 

Why? You can use a focal reducer with a Panasonic AF100 or Sony FS5 or Sony FS700 or Sony FS7, all of which also  have built in ND filters.
 
And has ZERO of the issues I meantioned about the ND adapter you linked to.

422 without going to 10bit as well wouldn't be a huge gain, don't want to still be stuck with 8bit.
An internal ND filter adapter doesn't seem realistic. Needs to be built into the camera.
And XLR-K2M form factor would be much nicer than YAGH styling.

More info is coming soon:

http://www.43rumors.com/ft5-no-full-gh5-announcement-photokina/
My thoughts is, please please please have this (in order of priority):
4K DCI 60fps 10bit 422 internal with no crop + IBIS + XLR-K2M style audio implementation (not add audio like the YAGH!!) + built in ND filter (if the RX10 can do it, why not a GH5?? Even better if variable ND filter like the FS5!!) + 240fps FHD + multi aspect ratio sensor (like the GH2).
Do that and I'll sell my wife, soul, and first born to get one.
 
 
Do check out the XLR-K2M, is a nifty Sony product which can be put on their mirrorless cameras, or even point and shoots!
I see no reason at all why Panasonic couldn't bring this out if they considered it. 
The Sony RX10 mk2 is priced way under US$2K, and has an ND filter. Even if they GH5 doesn't have the fancy FS5 ND filter and only has a basic RX10 type ND filter then I'd still be happy with that as a big improvement for the GH line up
As it looks like an AF200 is not coming, I think Panasonic really needs to bring their best A game with the GH5! And the GX9/G8 can be photography focused cameras, plus there is Olympus for MFT users.

If true then the timing is weird.
It's already quite overdue compared to previous release cycles for the GH1,GH2,GH3,GH4.
I wonder if they have had a late major change - such as new sensor - to incorporate?
All speculation at this point....

At this point the problem is not Canon but people that keep buying it.

I am just a guy with an independent voice in the world of camera reviews without hundreds of cozy ties to people from the manufacturers, without ads splattered all over the screen, without sponsors on my every video, yet still I find EOSHD mired in a world of cut throat rivalry. Only very occasionally like in the beginning with DPReview have I been given a leg up in this industry and even then it only takes one person like Barney to massacre that relationship too. The other blogs like NoFilmSchool, Cinema5D and NewsShooter spend 10's maybe even 100's of thousands of dollars trying to punt my homebrew EOSHD site into oblivion and I just find the whole thing utterly distasteful. Rather than offering a new talent an opportunity they instead I am treated like just another commercial rival to be beaten.
In the end it is up to you guys to choose. The managed platform of platitudes and advertorial, or the honest opinions and educational books of an artist/filmmaker.
May the best guy win.
