Halo: Combat Evolved Anniversary will incorporate some kind of Kinect support. This was revealed by Microsoft's Phil Spencer in speaking with Gamespot.
"Core focus for us in our press briefing this year with Kinect actually came from two sides. As a first-party, we believe Kinect will be important to all genres of games, be it racing games with Forza, combat games like Ryse, even games like Halo Anniversary has Kinect integration."
Sounds like Gears of War 3 may very well be the last Xbox 360 title from Microsoft without any Kinect on it.
