At the Kodak Theatre in Hollywood, Nintendo unveiled its forthcoming Wii console with a play through of Legend of Zelda: Twilight Princess.

It also has showcased the motion sensors on the controller that are free of the buttons. What it means, one can easily use them both in tandem. You can move forward and then push with the controller, causing Link to smack out with his shield.
Some mini games also will be associated with the controller. For example you can go to fishing in the game.
