Well it is a good thing that sony stole the idea AND MADE IT BETTER!
Sony's "wand" isn't the main controller by anymeans, it is just like the old rifle for the nintendo (You know for duck hunt
) so using that as an example Nintendo's controller is going to be the rifle and Sony's is going to be a controller with the option for the rifle for some games. I would love to see you play a racing game with the rifle shiek. Get my point? Nintendo has screwed up big, but Sony has taken the "good idea" and made a practical use for it that doesn't suck!
