According to IGN, LucasArts has canned the PSP version of The Force Unleashed 2. The game will still make it to the remaining consoles which strangely enough includes another handheld version, the Nintendo DS.
No real rhyme or reason was given as to why it was cancelled considering the first one sold just shy of a million copies, roughly the same amount as the DS version. Perhaps the Force was simply not strong with this one.
The Force will be unleashed for a second time on October 26 on all platforms minus Sony's PlayStation Portable.
