The Japanese Government have just announced that they intend to deliver 7680 x 4320 HD with 22.2 channel sound as their domestic broadcast standard by 2015.
They're calling it Super Hi-Vision.
They have called together a group of private companies and are providing the resources to make it happen.
Incredible stuff !!!

PS - Note to mods, perhaps there should be an HDTV news discussion forum as I couldn't really find the best place to post this. I think it's fairly big news but chances are it'll get missed by most members here.
