It's genius just like the Wii Remote with Wii Sports and the Balance board with Wii Fit were. It's a completely new way of experiencing video games, not just playing but experiencing. It's the kind of thing that got Nintendo into the number one spot this generation.
Also as I've said previously, Nintendo will now have brought key new genre's to popularity;
- Brain training
- Fitness
- Stress relief/Relaxation
Yes I think the Vitality Sensor has the ability to be as big Brain Age and Wii Fit. We'll see though, the software is the important part.
