Nintendo Wii Vitality Sensor still coming to a hand near you, says Iwata

For a product with the word "vitality" in its name, Nintendo's forthcoming Wii peripheral doesn't seem to have much of a pulse these days. The oddball controller certainly piqued our interest when the gaming giant showed it off way back in 2009, but aside from some false alarms and an uncovered patent application, we haven't heard a peep. Nintendo president Satoru Iwata addressed the Vitality Sensor's conspicuous absence during a financial presentation, chalking the delay up to "differences in biological information in humans." The peripheral is still coming, according to Iwata, but it won't be released until the company can make it work well with 99 percent of consumers -- a tall order indeed. And what about the other one percent? Well, perhaps they can try these on for size.
