Of course, it's not been confirmed, but the box art which just appeared on the Xbox Live Marketplace for Future Soldier might shed some light on another possible reason for the delay.
Go ahead and click that link. See that purple band at the top? "Better with Kinect Sensor", you say? Very interesting.
There's been no official word from Ubisoft as yet, but it appears that Ghost Recon: Future Soldier may be among the first titles to integrate the Kinect along with standard gameplay.
So what do you all think? How would you like to see the Kinect implemented if that is, in fact, happening?
