I have to agree with him.
Vitality Sensor is just a Heart Rate Monitor (HRM) and a HRM that attaches to your finger. Exercise equipment manufacturers have moved away from this sort of devices because they are clumsy and annoying to the user. They put the HRM in handles. People that workout either use straps or watches (I use a watch with a HRM in it.).
Nintendo may sell some Vitality sensors to people who use Wii Fit(+), but I think if the people were really serious about tracking thier HRM they will use a far more convient device like a watch. They arent that expensive. Maybe a Wii Vitality Sensor that is a watch that transmits wirelessly to the Wii would work, but that isnt what Nintendo has shown.
Its libraries that sell systems not a single game.
