If I worked at Nintendo

and made the Wii remote I would put a microphone port on it. Just like the microphone on Nintendo DS. Imagine talk, scream or sing while gaming. Why not put more interactive functions in games, maybe blow away stuff in adventure games or hold conversations with characters in role playing games. And karaoke games could take a totally different way on the Wii console. Sometimes companies could make things even better by combine their products.
