The eagle-eyed folks at NeoGAF have spotted the addition of a new DLC to the PlayStation 3 trophies of Borderlands 2 with the latest patch, titled "Mr. Tongue's Campaign of Carnage". Considering the predecessor "Captain Scarlett and Her Pirate's Booty" was outed the same way, I'd expect this DLC to be announced relatively soon, proving the NeoGAF user's findings true.
