If Canon is able to put a 24-100mm equivalent f1.8-2.8 in the G7x  which is tiny compared to the XC10, surely they can provide an even better lens with a similar focal length for the XC15. I know the slow lens tended to be the first thing most people complained about.

How big is your Hat Andrew!  The only way I see them getting 6k and that sort of MP is if it has a Super 35 sensor in it. Or, if they have come out with some really Magic electronics jumbo mumbo that is new to everyone, even them. I think it Has to have some oversized sensor in it to pull this off. They have done that with the GH1 GH2. So they are not new to doing it.

You know some people will actually buy a GH5 for the stills photography part LoL. I would think they would like it. And I am sure most of us will take a shot or two photo wise.

Oh man, if the FS5 had the A7S II sensor with IBIS, that would be brutally fantastic.

I use a Speedbooster Ultra on my A7RII in Super 35. Super 35 image quality and I get what amounts to FF when using my MF Contax/Zeiss MF lenses + gaining a stop ... so a little better low light capability. 

It's always baffled me why Sony have never put the a7s sensor into a small video body... you'd think it would be really popular with NDs, XLRs and a nice codec

Wow. Now I guess that explains why his posts have now been deleted.... 

Exactly but you forgot some
A7 series has the FF and noise control 
GH5 the recording specs..
canon the ergonomics..
We need Olympus stab, GH5 video specs (4k60fps and 10b422), Canon colours and DPAF and ergonomics, with an A7R2 sensor and with canon lenses. Now imagine that camera ? Fully stabilized with amazing AF, amazing sensor for stills, great DoF, great everything actually.
now one needs two lens system and two cameras to get 95% of this. 

If it is only 2.2x vs 2x crop, I don't see much point in being able to switch between the two. But if it has a 20MP sensor, then a pixel-to-pixel 4K crop would be a significantly higher than 2.2x final crop? Which could be worthwhile, as if it then makes your lenses a wider range of focal lengths. 

Handy for events for instance! If I want do shoot 4K from the back of the room and need a little bit of extra reach. 
 
100% agree! Ideally it would have full size HDMI + full size SDI
But even mini HDMI + mini SDI together would be nice. 
Doubt any sort of SDI would happen... but even so, double outputs would be very nice! Maybe full size HDMI + mini SDI? You could have full size HDMI going out to your external recorder, plus your EVF hooked up to the mini SDI with a LUT applied (ha, if the GH5 can have LUT support! :-D ).
In such cases a GH4/G7 with a fast lens will still be sufficient. 
We're not talking about a national level brand here! But a garage band doing a live performance, a GH4/G7 is totally fine for that. If you can't do that then: 1) you're having unrealistic expectations for a zero budget (or a few hundred bucks, same same thing) production which doesn't have to be perfectly 100% clean 2) you're not using an appropriately fast lens / focal reducer 3) you're not picking the right shots / angles for the edit
 
Yes I would like the GH4 a stop or two faster in lowlight, but would I trade that for the higher price and limitations of a Sony? Nope, but at least that option does exist if you want to go Sony instead!

Should Panasonic focus on this aspect first next above everything else? Nope, small things like crop aspect ratio markers or 4K 10bit 422 @ 60fps, or 4K DCI 24fps raw onto CFast / XQD cards, or full size HDMI, or movable EVF, keeping a low price, built in ND filters, multi aspect ratio sensor, etc etc etc.... all matter more than pushing the lowlight performance even further.
