Thanks a lot for sharing the survey link. This is a great opportunity. I own a JVC LS-300 and I love it. A better quality  camera of that type with a better screen and (very important) a simpler and more logical menu would be a great and unique C4K camera with XLR, BNC, internal ND filter...
The association of a S35 sensor with M43 mount is an amazing feature, as I discovered  that many M43 lenses are able (or almost able) to cover the S35 sensor size, widening everything... 
Voigtlander 17.5 mm, 25 mm and Panasonic 42.5 mm f/1.2 are among them
And with a speedbooster and FX lenses, you get that "Full Frame" look on demand.
No camera on the market are offering such a flexibility from S16 crop view at 120 fps ( I am using my vintage Cine Nikkor tiny lenses), M43 convenient compactness to FF look.

I chimed in and left my two cents. Full frame, anamorphic support, SDI, color science, etc, etc.
I also insisted that the camera have a shoulder-mounted form factor. I simply do not understand why people have their arms wrapped around the mirrorless style even for dedicated cinema cameras. We have 100+ years of cinema camera design behind us, and none of them looked like a stills camera.
In case you forgot what a real cinema camera looks like:

Give me that Super 35 sensor and M43 mount and take my money. 

For anything related to filmmaking equipment, eoshd is the place I am visiting, I also like News Shooter and for photography, cameralabs is doing a great job as reviewers.
Tony & Chelsea are sitting nowhere since I had seen them, in one of their video, holding the camera body only, instead of the huge lens (600 mm  f/5.6) attached to it. Absolutely NO professional relying on their equipment to make a living would do such a destructive move.
I am working with a GH5, which is a fantastic camera, and I am using it with manual lenses (speed booster + Nikon AIS or Voigtlander) for fictional work and music video, but I feel very frustrated while shooting personal life event (running kid) or journalistic work (such as yellow vest protest in Paris with tear gas in my eyes), as the autofocus is just so bad, losing target so easily and pumping like hell. Even my Nikon D5500 I carried once did a better job in video AF! A bit slow to grab something but much more stable staying on it.
On an ENG camera (HVX200 in the past, JVC LS300 now), I do not rely on AF efficiency that much as the ergonomic make it easy to switch from AF to MF to get the best out of both system, but in a crowd of protesters and journalists potentially targeted by flashball, I prefer to use the GH5 to be more discreet and faster to move.
I do think, that having a good autofocus system is lacking on all Panasonic cameras I used (GH1 to 5 + GM5 + G85) to get a complete and very efficient package for video work from fiction to journalism. 
If there is no serious improvement in AF on the S1, I am not going to invest my money on it. GH5 and JVC LS300 (an amazing camera with its FX look with a speedbooster) will still do the job for me.

Thanks a lot for that information I had seen nowhere else.
Sorry, I do not want to be too political, but this new project of law is just a sample of Europe way of dealing with its population: unadapted, against our will and destructive (for freedom and creation).
Brexit is a great opportunity to leave the Titanic before hitting the iceberg. How lucky you are to not depends on the Euro ! Switzerland is doing well with Europe being an outsider. Why not UK?
This Europe was wrongly designed for us. It is a bureaucratic monster that benefits to lobbies and costs a lot while forcing every country to adopt new laws (we had never been consulted for) which are not adapted to our need/life style/tradition/cultural difference. My country totally lost its  power of decision in politics and economy, we randomly elect a useless president every 5 years who is just obeying Europe, creating new taxes while destroying our country (industry, social balance, education, health care...) to please a European institution nobody had elected, but working hard for lobbies.
 

@Kisaha Thanks for your comment. Music was composed by a great guitarist who is from that area in France. Bretagne is a big part of Celtic world, full of history and legend. Bretagne is, for example, the land of Arthur and the Knights of the Round Table. 
Concerning your question I used the JVC at a max of ISO1600 and got no problem with noise, as I am always setting lights for my indoor shot and I also get a great range of lenses with a wide aperture when needed.
 
@Anaconda_ I am using this ND filter trick as well, but still, I have to use this terrible knob to get the right exposure on Lumix lens. I prefer not to count on the exposure correction too much during post-processing as this often deteriorate the image.  
The one push auto exposure was a feature I was used to on all the ENG camera I worked with for documentary (from Sony PD150 & Digibeta, Panasonic HVX200 & HPX 500, AF103...) and I am missing it here as soon as Log profile is selected. It can be very useful while moving (or panning) from shadow to light progressively while shooting. ND filter turn does not allow this.
On the LS300, I tend to use the aperture ring on Voigtlander or non-native lens with adapter (Nikon AIS).

Here is a project I mainly shot on JVC-LS300 camera in LOG mode.
The only limitation with Log mode is losing the possibility to quickly adjust the exposure by pointing the camera at something average and pressing the "auto" button once to get a starting point close to the exact exposure. Sometimes that limitation slows down a bit the process while switching from indoor to outdoor shots using Lumix lens as the aperture knob on the camera is not precise and not easy to handle.
B cameras were Panasonic G85, GH3, and GH4
 

I think you might be interested to discover those 2 videos
One is the trailer, one is the complete making of
IF you like car chase, stunt and exciting stuff, you should have a look
It is a remake of Fast and Furious made in China by the usual stunt team of Fast and furious
4 month shooting near Shanghai and I directed, edited and partly shot this Making of. Enjoy;
