Nintendo struck an early blow to Microsoft big day on Monday by announcing Wii MotionPlus, as small add-on for the Wii Remote which contains a motion gyroscope, this combined with the accelerometers already inside the controller promise to upgrade the current Wii Motion controls to 1:1. In simple terms, as you move the controller in the air it will be able to track your movements with absolute position and angle detection. So an obvious example would be the Star Wars Lightsaber game that we all want on the Wii. Even though you could argue that this technology should’ve been inside the original controller since launch, but seeing as most Wii developers aside from Nintendo themselves haven’t managed to get a decent control scheme with the current Wii Remote let alone a more complicated version.
