The microphone is true
I think I have to take this one before moving on. I saw in the comment that a lot of people think Im fake becuase I said it has a mic. Both Iwata and Miyamoto have told in interviews that the Wiimote will have no mike. But this is just a way to cover up. If they wont answer you know it's suspicious. And if they suspect it will have a microphone that means they'll ask about different implementations like chat and so on. If they say no it has no mic, then noone will ask about it again and they will just forget it. Instead of maybe answering more and maybe they will slip. So it's easier to do this, and they can always say oh we added that later, so we didnt lye anyway.
Because a mic can do very much with a game. There are many interesting ways to use it. For example Nintendo copyrighted WiiKaraoke as a trademark. So that's just further evidence.
A mic is NOT expensive. A mic is one of the most basic, cheapest key components a controller can possibly have. It's easy to put there, it consts practically nothing and unless it's activated it draws absolutely no power from the battary. So personally, I think you should can see that it would actually be stupid of Nintendo to NOT put a mic in the controller. At least I think so. It's an extra element that costs not lower battery life, almost no money, and can give so much back. Even activated, it draws very little power. It takes some extra to send the data to the Wii, but that's very little.
So basicaly, I think it's easy to see both that the Wiimote will have a mic and why Nintendo claims they have no mic in it.
