'Tron Legacy' Sequel Getting On the Fast Track 

Although Tron Legacy is still more than six months from release, Disney is already fast-tracking a sequel.

According to the Heat Vision blog, Edward Kitsis and Adam Horowitz, the Lost writers/executive producers who worked on Legacy, have begun writing a follow-up film.

While details are slight given the early stages of the project, HV notes that some topics to ponder include whether the sequel will focus on spinoff characters or center on a new adventure set in the Tron world.

Insiders have suggested that Kitsis and Horowitz are working on a way to round the story into a trilogy. No deals have been made with Legacy director Joseph Kosinski or cast members to return. However, options were placed in the original deals.
