I don't know if any other AVSers are here at Siggraph, but I just saw the future of HDTV. A consortum of Japanese companies, led by NTT, is demoing a proposed future HDTV system with a resolution of 2048 by 3840. It has an aspect ratio of 1.875 as opposed to the 1.77 of current HD. It also has less color space compression, with a full 8 bits per channel RGB. It's designed around 24 fps, but displays at 96 fps.
The prototype display device is by JVC, and has some glitches. There are areas with stuck on and stuck off pixels, but overall it's the finest HDTV I've ever seen. It shows great promise for the next generations of D-ILA especially with black level. But it was the smoothness of the image, and the astonishing color quality that is really worthwhile. If you are in LA, I'd consider it worth your while to pay the $65 on-site exhibits-only fee to see this (of course there's plenty of other cool stuff as well.)
Note: I have no connection to JVC or any other company involved. I just think it's cool.
