No, its no joke. It's the official Sony PS3 controller. It's exactly the same as the old one, save there's no cord. The plug is most likely for
A) charging (although there's no rumble this time, thanks to the lawsuit, so less energy needed)
B) attaching a cord (duuh)
C) somewhere to stick your ipod (ipod-users stick it everywhere they think it fits)
D) dirty deeds done with sheep
And it's Bluetooth and it's got a gyro, which they stealed from Weeeeeeee. Of course, it's not as funky as the original.
If you still dont believe me, click the below link. See, it's got porn in the url.
