lots of replys to this that i dont feel like reading, so if my view has already been stated sorry.
if nintendo WANTED wii owners to have voice chat (wich they dont, it's never going to happen, i'm sorry to tell you all this it just wont) then they would release an official wii headset instead of an update for that microphone. theres 2 reasons why
1:make money because every wii owner would buy them and they would be jsut as hard to find as the wii itself
2:how many people that own wiis do u think actually have that stupid mic? lol
but mainly money. nintendo is all about money, their a corporation of course they need to make money. (i'll admit their not as bad as microsoft though lol)
