LucasArts has posted several job listings indicating a new, yet to be announced FPS is in the works from the company.
Most of the juicy bits are revealed in the job description of the team's Senior Core Engineer position, which makes mention of the task of implementing ‘features and optimizations on current and Future Generation console and PC hardware.'
The company posted four total positions including the aforementioned Senior Core Engineer , Senior AI Engineer, Senior Animator, and Gameplay Engineer. The Gameplay Engineer requires proficiency in Unreal Engine 3.
A new Star Wars FPS is certainly a strong possibility, but at this point nothing has been confirmed.
