You know what the Wii needs? More poorly-conceived peripherals! Oh look, here's the WiiThink, a concept controller that makes no sense.
You see, the WiiThink is supposed to be an EEG sensor that monitors brain waves.
It's designed to get the elderly to think real hard so their brains exercise and they don't get Alzheimer's.
The problem? There is no evidence that thinking hard prevents Alzheimer's. It's a disease, not just the result of an underused brain. So let's go ahead and leave the WiiThink as what it is: an unmade concept.
