User blog:Yoshi-TheOreo/Borderlands coming out with more DLC?

I'm not sure if anyone has heard, but I read somewhere on a forum that the creators are planning to come out with more DLC for Borderlands. Question is, what will be the plot? Even so, will there be a raised level cap? New weapons, mods, enemies? I can already see a DLC of taking on Atlas again, but this time fighting General Knoxx's commander who is a five year old kid. Possibly one where they actually get into the four main characters' story lines. (Brick and his missing sister, Lilith and the remaining Sirens, Mordeci and his investigation on that murder, granted if all these I read on this site are true.) But what else can they do besides come up with a totally new game instead of more DLC?
