1920x1080 is the holy grail of HD. (It's been the standard HD resolution for ages - despite what TV manufacurers try to sell you.)

These new holographic discs are amazing, but HD-DVD and BlueRay are both capable of holding a full movie at 1920x1080, that much added storage isn't needed for consumer movies.

Those discs are VERY, VERY cool though. I could use something like that here at the office! I play with 5,6, and even 8k images all day. The more storage space the better!
