Borderlands has received two DLC packs so far but more is on its way. According to Randy Pitchford, CEO of Gearbox Software, “There will be some announcements on both [free updates and paid downloadable content] soon.” We speculate that the upcoming patch will include some free bonus content, though most of the new content will only be available by purchasing the new DLC packs.
Speaking to IGN, Pitchford also said, “We have a lot of motivation to do more with the game and have a lot of lessons we’re applying not only to our immediate efforts, but to our ambitions for the future. I don’t have anything specifics to announce at this time, though.”
