More information and some new videos have come out in regards to this camera.
This sensor is found to have about 11.5 stops of dynamic range which is not unreasonable although we were hoping for a bit better. The image so far seems to be pleasing and have potential when properly exposed.
See the following new videos as well as an article about the JVC GY-LS300 from the News Shooter website:
JVC has announced three new 4k cameras.
Pictured above is the GY-LS300 ($3,999 USD), a Super 35mm camcorder with a Micro Four Thirds lens mount. Expected to ship in April around the time of NAB.

The following are the only samples we have for now of these camcorders:
