Few details are available for the 3-disc Blu-ray edition, but the set includes a single dual-layer Blu-ray disc and two standard DVDs. Interviews and a theatrical trailer fill out the release's supplemental package.
Update Warner Brothers are listing this as a blu / hd DVD / DVD combo disc so
Looks like it is being released !!
Cool
Have you got a link to the Warner Brothers' webpage for Gantz?
