Nintendo 'Cannot Clearly Say' When Wii Vitality Sensor Will Come

IGN: "During the Nintendo Financial Results Briefing, Nintendo of Japan President Satoru Iwata commented on the lack of Wii Vitality Sensor news. Iwata stated that the Vitality Sensor's delay is due to the company's commitment to maximum usability.

"If it was acceptable that only 80 percent of the users thought the result was natural, then we could propose this to consumers right now," Iwata said.

Iwata said that Nintendo is trying to overcome the hurdles of "large individual differences in the biological information of humans" and that these difficulties prevent the company from confirming a release window for the peripheral."

The story is too old to be commented.
