Own a Wii? Well, you controllers are about to become obscolete thanks to the new Wii MotionPlus add-on that's coming on June 8. In order to get the most accuracy out of your precious Wiimotes, you'll need to spend $20 per controller to bring it up to code.
The Wii MotionPlus is a small block that plugs into the bottom of current Wii controllers. It adds another level of sensitivity to the motion-sensing technology inside, letting the console detect much more subtle movements. No games currently support the add on, but look for more and more to support and require it as time goes on. Awesome?
