The PS3 Trophies Forums have tidbits from the newly released Mechromancer DLC for Borderlands 2. It seems the new content for Gearbox's role-playing shooter sequel adds some references to other upcoming content, and they seem comfortable concluding this is an expansion called Captain Scarlett and Her Pirate's Booty, which apparently has nothing to do with Gerry Anderson's marionette Captain Scarlet. They have more details, which are not confirmed, but if they are accurate, could probably be considered spoilers. Thanks Shacknews.
