Ok are we going to be getting a DLC which allows us to roam the wasteland like broken steel did? and will we have to wait until that DLC # for it? I seriously hope so since in FO3 I would roam around and collect atleast one of everything and repair it to full and store it away. I can still sort of do that but it a little harder with faction relations and the fact that this game is so script heavy that it can crash if more than a couple of quests are open and one is basically stuck open since you have too save before ending to explore.

There will be NO Broken Steel like DLC for New Vegas.

No and I'm glad. New Vegas's story is so deep and as Broken Steel did it would ruin the story choices you make. In FO3 Bethesda couldnt even account for 2 different endings so what makes you think obsidian could account for the 50+ different endings in New Vegad. If you want to free roam do it before the game is over.

They confirmed that there will be no game ending extending DLC. Download a mod to play after the game if you wish.
