Contrary to some earlier reports, LucasArts will be making an appearance at E3 this year but will be using the forum to pump up already announced games such as Fracture, TFU and the 2 new Nintendo Clone Wars games. From Venturebeat.com: "While (LucasArts rep) Grohne wouldn’t comment on any unannounced titles, she did say that E3 won’t be used this year to announce any new games from LucasArts because there’s too much noise surrounding the show."
Let's face it, how many new games could they announce this year anyway? They have to save something for the future...like KOTOR 3 right? :)
