According to this Hollywood Reporter story on Yahoo News, Monolith is currently working on a first person shooter based on the classic movie Tron (thanks AVault). There aren't any details beyond the fact that it's a "first-person-perspective action game" and is being developed for the PC, with an Xbox port likely (whether or not the fan-favorite light cycles will be making an appearance is unknown). Also of note for geeks is the news that Disney is preparing a 20th anniversary DVD release of the original film, and that things are progressing (albeit slowly) on a sequel.
