Remember the Xtion Pro and Wavi Xtion motion sensors that Asus showed off at CES? Well, fast-forward six months and there's already an updated model on the market: the Windows- and Linux-compatible Xtion Pro Live. The new version complements the original's IR and depth sensors with a Kinect-like VGA webcam and a pair of microphones, while also jacking up the bill to a distinctly un-Kinect-like 175 Euros ($300). That price tag won't make us shift our living room furniture around anytime soon, especially since Kinect is already officially heading to the PC. However, that isn't really the point: the Pro Live edition is primarily meant to help developers design better games and apps for the more consumer-focused but as yet unreleased Wavi. Soon as they develop a game that rewards rather than punishes us for dancing like Tina Turner, we'll be right there.
