as for your question
the Wii is capable of bluetooth technology and could easily incorporate a kick ass wireless headset for use in games like Brawl, Kart, anything really
However, Nintendo prides itself in its family friendly image. hell they have to!
The reason the Wii has sold 20 million plus, and has the highest attach rate, is because it appeals to those who were not previously inclined to play video games.
this relates to the headset because Nintendo fears that incorporating a headset into a game like Brawl would threaten that image Nintendo strives to hold. if anyone could say anything to anyone else during a game of Brawl, then that means, potentially, a 35 year old man could tell a little 8 year old to F*^% off, and well you get where this is going
bottom line...No headset...We as fans will complain, but it wont change anything.
