Randy Pitchford has confirmed that Gearbox are planning on releasing additional downloadable content for Borderlands 2, beyond the planned Season Pass content drops that were announced last month.
In a Q&A with fans on Kotaku, the studio boss revealed: "The stuff we're planning and working on for the Campaign DLC Season Pass is big DLC stuff," though he later added: "We will have other, non-Season Pass related DLC. The additional character (Mechromancer) is one kind of example."
So, if the 60+ hours of Borderlands 2 content isn't enough to satisfy, you can rest assured that Gearbox are thinking of you, and additional DLC is on the way.
