Gaffer Tape, depending on which country you're from there are a few versions. There's the two-disc Deluxe Edition, the single disc Widescreen and Fullscreen Editions and then in a few places you can also a Collectors Edition that contains the two-disc version, the CD soundtrack, a 72 page comic book and four cards.

I'll be getting one of the two-disc versions, I usually don't bother with the packaged versions but the price isn't too different here and it will be released during the initial launch (unlike most other DVD packages) so I might consider it.

[edit]Actually, it looks like the online store I was looking at just confused the issue! I believe the comic book also comes with the Deluxe Edition.[/edit]
