You wouldn't get rich even if you won. The trial lawyers would walk away with a huge chunk for themselves. If it was a class action suit, the remaining money would be split up among star wars fans (the plaintiffs) who had been "harmed." It would probably amount to a coupon for the new dvd's at half price so long as you filled out a bunch of confusing paperwork.
The only good that could come of it would be raising awareness. But I think that would be mostly negative publicity.
Not worth it!
