Hopefully that December DLC expands the game world. This game needs way more areas. What we have wasn't nearly big enough at launch, nevermind almost a year after release.
Not going to happen. Dlc 2 is also a small one, just adding instanced arkfalls and stimspikes and such. THey say they will start getting into meatier stuff with Dlc 3. So I am afraid you have to wait atleast until then.
