If that's legit, that's some pretty hefty shit. I know a lot of kids that will be very sad. Me- I'm a Nintendo and PC kinda guy (have a PS2, don't really care for it).
this will never hold, they've been selling and making dual shock related products for nearly a decade. it's gonna be like these morons that wanted to sue every company who makes 3d games because of some vague patent.
i think that its pretty bad, i am a ps2 owner but havent bought games for it for a long time now, just because I built a pc and found that it is far better than teh ps2. There are some good games there too, like GTA Vice City and the Gran turismo range, plus metal gear solid. Its a shame really.
