Fallout: New Vegas will be a “non-sequel” by Obsidian Entertainment, who is best known for Neverwinter Night and Knights of the Old Republic. I’m going to take a guess and assume it’ll be based in Vegas, but the only real pieces of information I know so far is that it’s not a direct sequel and that it’ll play a lot like Bethesda Softworks’ Fallout 3 in terms of gameplay. Obsidian is aiming for a 2010 release on PlayStation 3, Xbox 360 and PC.
