According to The Force-Cast, Star Wars: The Force Unleashed is scheduled to continue in 2009. On the latest episode of The Force-Cast, at about 1:41, Rebelscum’s Dan Curto said that “there is something happening in 2009 regarding The Force Unleashed.” He also mentioned that Lucasfilm would probably kill him for saying it. What will it be? New levels? More costumes? The long-rumored multiplayer add-on? Curto couldn’t say, but he could confirm that the TFU figure line will be coming back, too. We’ll keep you updated as more news

pls let it be a PC-release
I would love it to be about Mara. That would be awesome and a half.
pls let it also be Xbox 360-release.
@Styto: Sadly, I doubt it will be released on PC. LucasArts has said no to a PC release multiple times.
@Rudy M Alapag: It is already on Xbox 360! You can go out and buy it right now!
