"Kinect PlayFit," first seen in leaks, is now officially announced – and officially released today! That means we can finally understand what Kinect PlayFit is: a special "fitness dashboard" that tracks your calories lost across multiple Kinect games, "from Dance Central 2 to Your Shape Fitness Evolved 2012 to Kinect Star Wars," according to Microsoft. The dashboard also features leaderboards and social "activity challenges," two ideas that probably either motivate you to keep up your fitness routine or make you feel very uncomfortable, depending on how fit you already are. It even has its own Achievements.
