Apparently a Clone Wars game that will run as a companion to the upcoming Clone Wars animated film release is in the works over at LucasArts. This all comes from IGN which claims that a picture of Obi-Wan and Anakin in the manual for LEGO Indiana Jones indicates a fall release of something.
Merely a rumor of course, but another Star Wars game couldn't hurt, especially since it's part of the story we haven't been able to play through, that being the space between Eps. II and III that weren't covered in the films.
