This website has a listing for a community trademark filing in Germany from Bethesda Softworks for Fallout: Shadow of Boston, as computer game software title. There's no corresponding entry in the United States Patent and Trademark Office database at this time, but this can still provide fuel for speculation about a possible next installment in the post-apocalyptic RPG series. Thanks NeoGAF via DSOGaming. Update: Bethesda tweets this is a fake, saying: "The German trademark filing that's making the rounds is a hoax. This didn't come from our offices."
