Why is Kinect so laggy? How Microsoft's new controller fails to inspire new gamers.... Project Natal fails to deliver!

Microsoft promised so much and now that the chance to launch Kinect (project Natal) is about to arrive so has it delivered? Looks like the answer is NO! With reported lag in the Kinect system and videos posted daily show the lag between gamer actions and game play what can Microsoft do? Did they include a contract with game testers NOT to publish lag reports before launch? Watch this top notch developer video (until it's taken down) from the US Jimmy Falon show.
