Bethesda released the first teaser trailer for the next Fallout game today. They’ve previously said that Fallout: New Vegas is not a direct sequel to one of the standout hits of 2008, Fallout 3. Really? From the looks of the trailer, you can be reasonably sure that FNV is at least going to offer a very similar experience. California-based Obsidian Entertainment (Star Wars: Knights of the Old Republic II, Neverwinter Nights 2) is developing it. Expect to play it sometime this fall.
