There is still plenty of time until the release of Borderlands 2, but as with any major release there is going to be a Collector's Edition. But Gearbox are still pondering what to put in it, and have asked fans to come up with suggestions.
If you have an idea or thoughts on the subject you can head over to the official Gearbox forums, and make your voice heard. How about a small Claptrap action figure or a Psycho head to place on your table?
