Hello guys,
Here is my guess, a possibility that I haven't read anywhere. You have probably already watch this video: http://www.youtube.com/watch?v=ZzRq7GhBLRQ. The last part is the important one, I have made a gif to make it clearer: 
I think that Nintendo will use the camera to track where the extremity of the stylus is quite like the pointing aspect of the PS Move but without motion controls. It could determine where you point your stylus and how far you point it from the screen and of course it will use this data to interact with the game. I think it will be perfect to have the impression to interact with 3D elements.
