Coming not even an hour after reports that developer Bethesda had registered new trademarks for both Fallout-related movies and TV series, the studio has made a surprise announcement at a London event that a new game in the franchise — Fallout: New Vegas — is due for release on Xbox 360, PS3 and PC in 2010.
It’s not Fallout Tactics — it’s not Brotherhood Of Steel. It’s another Fallout game. It has no impact on what [Bethesda director] Todd Howard and his guys are planning.
As Gamasutra notes, a number of Obsidian employees are former staff of original Fallout series creator Black Isle, who famously had begun work on their own Fallout 3 coded named Van Buren as early as 2003.
