7680x4320?!? Hatchi-matchi that's some serious resolution. The cameras required to capture images at this resolution are only monochrome prototypes at the moment, so don't expect to be upgrading your HDTV anytime soon.

"To get a picture of the bump in resolution, a Super Hi-Vision image could be approximated by tiling 16 of today’s best HDTVs together. In comparison, a 1080p picture represents a six-fold jump in resolution over standard-definition television."
