A description on the online-portfolio of concept-artist Keith Thompson has further substantiated rumors concerning a potential sequel to Borderlands. Thompsons website has recently been updated with several pieces of concept art for the Guardians found Borderlands, as well as several concepts for alien weaponry. The artist states that his work mainly concerned designs for the alien civilization found in the game, the story, and ‘The Vault’, which forms a central element in the storyline. He adds that much of the art produced by him was not used in the eventual product that was launched in October 2009, and states that:

Much of the art not seen here may be used in DLCs or Borderlands II.

Speculation concerning a sequel to Borderlands was already incited in November last year, when the Creative Director of Gearbox Software Mike Neumann that the decision to make Borderlands II “seems like a no-brainer”, given the success of the original. However, a sequel has not been formally announced. Take-Two, the publisher of Borderlands, recently stated that it intends to continue providing downloadable content for Borderlands.
