The home-release of Pirates of the Caribbean: At World's End (US release, at least) has been confirmed for 4 December 2007. It will be available in both basic DVD and Blu-ray.
There will be a single disc edition, and a 2-disc special/collectors edition.
I believe that whatever doesn't kill you simply...makes you...stranger.
