If Wii Sports Resort wasn't enough to get you excited over the MotionPlus technology for Wii, developer AiLive has the answer.
The company has posted a tech demonstration of LiveMove 2 on its website, a piece of middleware designed to help studios take advantage of the new sensor.
As shown in the video, the software recognises vastly different sword swings and thrusts in true 1:1 motion.
It also features a virtual lightsaber controlled in the way we've wanted since Nintendo first started talking motion control.
We'd recommend hitting this link right now and skipping to about 1:50, where the good stuff starts.
