Why do I need a kinect for voice commands?

Why? Seriously why can't they just use the normal mic + Xbox for this? Is it not possible? Or is there some kinda voice decoding thing in the kinect I'm not aware of?

of course its possible otherwise, for example this ps3 game uses voice recognition through the ps eye :

but in terms of this industry who ever hypes the hell out of their product gets recognition first...
