E3 Microsoft Studios Phil Spencer said that most likely all future first party titles Microsoft will have some kind of optional support for Kinect. Spencer said that it is not necessarily something that disrupts the gameplay, but may be a small addition that will enrich the experience as speech recognition seen in Mass Effect 3 or tracking the head of Forza Motorsport 4.

Spencer, however, explained that there is no imposition by forcing Microsoft's first party developers to integrate support mandatory Kinect: it will be added when it has meaning. What we expect Halo 4 "with Kinect better"?
