More Borderlands Mayhem?

Other than a somewhat brief quote from Take Two Interactive’s [TTWO] Ben Feder about continuing Borderlands support via add-on content, there is less than any real information about a potential upcoming fourth DLC pack for the popular “RPG shooter” game. And it is certainly possible that his statement may have been taken out of context or merely misunderstood. Is he referring to new content, or repackaging of the existing three DLC packs?
