IGN usually states release dates, but more than half are usually incorrect, if a specific release date hasn't been announced. And in the current case with The Force Unleashed, now specific date has been set other than February 2008.
November 30, 2007. Amazon have this (wrong) date listed even. Oh then again they have listed a (PC version) as seen on the other thread. Mayne there WILL be a PC version. But if anything it would be released no sooner than the weaker console, like that PS2.
