The PSP has 99 problems and the Force Unleashed happens to be one. For some “undisclosed reason” LucasArts has decided to cancel the PSP version of Star Wars: The Force Unleashed 2. Maybe they took a look at the piracy numbers, ran a couple of formulas, and determined that the profitable of releasing the Force Unleashed 2 on the PSP would not be financially feasible. Either that or Dark Sidious enacted Order 66 to wipe all PSP’s off the face of the planet.
