Thanks Pat. The official webpage for the HM100U is:

1/4" prog CCD so there's no rolling shutter to deal with. Records straight to Quicktime .mov files at in MPEG2 35mbps. Looks like they are using some sort of pixel shifting to get 1920x1080, unlike the Sony EX series, but those aren't very small nor light. Sounds like a great B cam to compliment the bigger cameras.
The biggest issue is housing manufacturers historically shun JVC. Only Ikelite and Sealux even consider JVC. The good news is that the massive XLR handle can be removed but it's still sorta in between compact camcorders and the bigger sensor cameras so many pre-existing housing molds won't fit it exactly.
Looking at this camera now, with Vidslr coming (wait for the big manufacturers response to Scarlett
), it's not exactly industry shaking. But it is the ONLY small form factor 3x CCD recording at full 1080p raster. It'll be interesting.
