Interesting. I wonder if it will be video or still photo equipment, or both.
It could even be AUDIO stuff, recorders, mikes, etc.
Looks like some initial details, basic specs, and three images here if you scroll down:
Also brief details from JVC on three MFT cameras:
Not surprised that it's a video camera. But it seems odd that they have a super 35 sensor but m43 mount. How many of the m43 lenses will cover the whole super 35 frame?
I saw the announcement but I am not sure what to make it of it. Some of the newer links help. With BlackMagic announcing a studio camera, I see the JVC announcement as bringing more firepower to m4/3 serious video.
more details here:

Quite an achievement !
Missed it by that much: https://www.mu-43.com/showthread.php?t=62866.
The Sigma and (most) Rokinon lenses will cover -- they're designed for APS-C which is basically the same as Super 35. Not sure about the others -- there could be distortion or vignetting on the sides. Maybe it will be a multi-aspect sensor.
The two first links appear to be cameras, while the third one is the Gimbal that can be used with the second camera. The whole gimbal concept is very intriguing. Will make for very nice fluid motion whether handheld or attached to moving vehicles etc.
The camera looks to be capable for m4/3 lenses as is because there is Olympus 45mm f/1.8 mounted on it. And AFAIK the m4/3 standard like the 4/3 doesn't specify sensor size but the circle size and if Super 35mm fits to it, then there is no problem as every m4/3 lens needs to cover same circle area.
I'm no expert, but it might even be possible to play with flange distance since there is no mirror to worry about.

So it can go up to super 35mm but can also shoot in a cropped mode. 21x11mm/19x11mm should be good for m4/3 lenses. For full super 35mm you would have to adapt a lens which is easily possible with the m4/3 mount and probably the reason they chose it.
One thought. The image circle diameter has to be a little bigger than the 4/3 sensor diagonal of 21.6mm, so that IBIS can work. The sensor needs to be able to move "off centre" for IBIS, so the image circle would need to be as large as the bounds of that movement to avoid vignetting more in one corner than another. If these JVC video cameras don't use IBIS, then they could use that "leeway" to fit a slightly larger diagonal sensor behind the lens.
No, the flange distance has to be precise or lenses designed to the u43 standard won't focus properly at infinity.
Or put another way, you could change the flange distance but it would no longer meet the standard and current u43 lenses wouldn't work right.
Thanks for correcting me - as I warned, not an expert
That is how i see it, as IBIS already requires extra space, it is possible. Just like Panasonic had wider sensor in its cameras for multiple ratios.
Haven't had time to test but if someone would first meter the distance from sensor surface to bajonet surface and then position lens front of the lamp and place flat surface as focused correct distance and meter the circle diameter, it would tell how large diameter we actually can get. Of course if there is already known diameter, it is easy
I can't even believe JVC would use m4/3 if user can't use all m4/3 lenses. Or olympus/Panasonic to allow them to use and market the standard unless it is compatible.
Prediction, it will be priced well but will be a poor performer- blown highlights and reduced dynamic range........every JVC product I've had has been on the low side in performance.........I'm not expecting any greatness with this camera- but who knows!
