Kinect and Eye won't be replacing controllers any time soon. The idea of driving a car with an imaginary steering wheel was just stupid and not compelling at all. Or pointing your hand at the screen like a gun. For traditional games, you'll see them used to augment control. Rocksmith 2014 is a good example. It seems to have voice control from the stage demo, and that's great because picking up and putting down a controller sucks when you've got a guitar strapped over your shoulder. There's possibilities with biometric feedback, head tracking, additional gesture controls. Eye can track the DS4 controller, so you have some motion control in that. It looks like Kinect may be able to do that a little bit, with unknown accuracy. There was an onscreen demo of someone lifting the controller to raise a shield.
What can be done with a gamepad is pretty much at its end game. You can't keep adding more buttons. There is already a push to simplify controls to make games more intuitive for new gamers. So we get voice and motion controls. That's the only way they can really do new things. The touchpad on the DS4 should be useful for a lot of things as well.
Edit:
You also have smartphone/tablet control. With Xbox One and PS4, I'd find it undesirable to have to switch between a control and a tablet. To me they are more suited to different styles of gameplay than augmenting what we currently have. The commander mode in Battlefield 4 is what I'd consider a good use of the tablet. Using a tablet to manage inventory is not. Wii U got that one right by putting the screen on the controller.
There are just too many logical uses for cameras and microphones for them not to be included in designs for future consoles/gameplay. Obviously Microsoft is banking on that a little more by their inclusion of Kinect as a requirement. I'm interesting in seeing what they do with it.
