The DLC for the game will be "Insane" according to Curt:
"I think you guys will really like some of the post launch things we do, beyond DLC.
I can say this much, barely, I was in Baltimore yesterday for a milestone and one of the later DLC packs was being shown, and I can comfortably tell you I've never played a game that had deeper or bigger content in every DLC pack planned. It's big, it's huge, and it's awesome. Their DLC plans are insane, and they're stunning.
To the point above I also think you guys will LOVE some of the post launch plans and how they get you to go out and around in the world, regardless of whether you've hit cap or not, there will be very cool reasons and ideas behind getting you around and in the content beyond the questlines at launch and DLC.....
