The 4K Varicam with a small recording pack that harnesses AVC-Intra444 to its full potential, a modular form that optimizes field operability, and a sensor that faithfully reproduces a full 4K frame. We expect it to be welcomed in the world of 4K2K mastering.” Kunihiko Miyagi Director of Pro Video at Panasonic

Seems like paper announcment for now.

"the camera looks to sport 3 separate units which may be upgradeable with new technology from Panasonic like their AVC-Ultra codec."

I'm glad to see so many new codec variations. I hope they will put a new one in the GH-3

The newcomer here, Class 200, will be a visually lossless codec supporting 720p, 1080i, and 1080/24p and 1080/60p. Bergeron said Class 200 would be suitable for ingesting tape-based media with no visible quality loss.

The new Class 444, aka AVC Intra444, is a 12-bit codec geared toward 1080p, 2K, and 4K media. It will be carrying 4K footage at about 400 Mbps in the Panasonic booth during the show.

AVC LongG is a 10-bit 4:2:2 codec that produces footage of a similar quality to MPEG-2 at about half the bit rate.

AVC Proxy, which scales from 800 kbps to 3.5 Mbps, depending on the bandwidth available, is geared toward cloud-based production — and probably those same news shooters Avid is targeting with its Interplay Sphere edit-anywhere system. At the highest quality level, AVC Proxy will carry an uncompressed audio signal.

Now that's an ugly camera. But I'd like to know more about AVC-Intra444
