Gearbox just announced the specifics of their special/limited/collectors editions of Borderlands 2 and they are pretty damn sweet.  There are two different versions and my interest is in the Ultimate Loot Chest Limited Edition.  Mostly because I want the loot box, but the rest is good to have.  Here is the details of each one (click the names for images showing the goods)

• Ultimate Loot Chest Limited Edition ($149.99):  Contains a metal game case, certificate of authenticity, creatures of Pandora ID chart, four lithograph postcards, Marcus Kincaid bobble head, art book, cloth map of Pandora, downloadable comic book, four stickers, and a freaking loot chest replica.
• Deluxe Vault Hunter’s Collectors Edition ($99.99):  Contains the Marcus Kincaid bobble head, art book, map of pandora, downloadable comic book, and four stickers.

I’m drooling over the loot chest.  They say you can pre-order them now, but I haven’t found a good pre-order spot yet.  Keep an eye out for them! *UPDATE* It looks like Amazon has it up for pre-order here.
