wii.qj.net are reporting (as a rumour) that the presence of a speaker on the Wii mote will soon become even more crucial than we thought. The rumour is that a microphone will also be on the mote and the remote will then double up as a VoiP phone so you could call people through your Wii. This has a certain amount of credence. The size and shape of the Wiimote transfers well to a phone, also the "WiiConnect 24" would also mean we could receive calls anytime. And depending on the strength of the mic you could also use it for games. They go onto say how the "grapevine" says that it'll also be used for video calls... which would mean we're still to see a Wii camera, something that was rumoured waayyy back when the console was unveiled but was never picked up on.
So the wait for more info goes on, stick with C3 as and when we get confirmation on the final Wii secret!
