If this post
at Lakitu's Lair has anything to say about it, the controller for the Wii will have a mini speaker and what seems to be a mic. What's so nice about this you may ask? Well imagine gun shot sounds coming from the controller instead of the gun. There might even be a possibility of talking in one controller and have the voice be repeated on another controller.. perhaps over the Internet even. Sounds pretty interesting if this is true.
