Hulk (Ang Lee) / Sept 16th

[Darth Lavender]

You haven't seen the HDDVD, I'm guessing.

Heck, the three hour King Kong (including three hours of U Control) is still considered one of the best demo pieces available, and the Blu-Ray TMNT looks incredible, at less than 15 gigabytes (including all the extras)
For that matter, Planet Earth fits almost three hours of incredibly sharp imagery onto each 25gig disk.
