Apparently GearBox is planning to offer a Collector’s Edition for their upcoming game Borderlands 2 (due out sometime in 2012). Not only are they planning to offer a CE they’ve asked the community to help them decide what to include!
You can send them your ideas on the official GearBox forum.
Me personally I told them I don’t care what they include for bonuses as long as the packaging is high quality. I figure I spend more time looking at it sitting on the shelf than anything else, so it might as well be worth looking at.
… although an RC claptrap would be pretty cool…
