Pitchford did not give any details regarding what will be included in the forthcoming DLC pack. Earlier this month, he confirmed new DLC for Borderlands 2, saying during a podcast, "We've got more stuff in the hopper that we're planning and getting pretty excited about."
Previously released Borderlands 2 expansions include Tiny Tina's Assault on Dragon Keep, Captain Scarlett and Her Captain's Booty, Mr. Torgue's Campaign of Carnage, and Sir Hammerlock's Big Game Hunt.
These expansions are available as part of the $30 Borderlands 2 Season Pass or individually for $10 each. It is not clear what the new content will cost or when it will be released.
