Warner Home Video announced two Blu-Ray editions of The Dark Knight to street Dec. 9. The limited edition will come in a Bat-Pod display case and, if the art is correct, looks to include a small replica of the motorcycle.
Amazon has a sign-up page for the Blu-Ray release, and it will likely flip into a pre-order page shortly when the SKUs come through.
I wonder if there will be an in-video option to toggle to pillar boxing just for the IMAX sequences. On a TV it actually will reduce the viewing real estate, but you'll see the full frame of the IMAX print.
