People, people.people,
Halo 4 would be much better with kinect, You will play halo 4 with the controller in the same way, but with kinect you also have the ability to strafe left and right with your body and peek over objects by moving your head up.
This will give kinect players a slight advantage, but wont mean you need it.
Also watch out for a few new single handed controllers coming next christmas
