In an investors' discussion with Nintendo president Satoru Iwata, the man behind Nintendo confirmed that the Wii Vitality Sensor is dead.

Amusingly, the Wii peripheral, which is designed to detect life readings via a finger clip, is no more. Iwata highlighted to investors that "after a large-scale test of a prototype inside the company, we found out that for some people the sensor did not work as expected".

Nintendo were considering releasing the product that worked for 9/10 testers but Iwata admitted "knowing that a product has a problem we should not launch it for the sole reason that we have already announced it".

What are your thoughts on the news - should Nintendo have released the Wii Vitality Sensor?
