Vitality Sensor's applications in traditional games are going to be minimal and gimmicky, if at all. The Balance Board has more to offer in that field than the Vitality Sensor could hope for. I also honestly think that this "horror game" that Reggie and Iwata keep tossing around is a red herring to stall the ire of the internet, in that such a game won't come from Nintendo, but is merely a possibility that someone else could work on.
I do think, however, that this little thing could really broaden the spectrum of what Nintendo is trying to do with "lifestyle games," and really branch out from the Wii's current conception of Fitness (as an active engagement), to an overall idea of Wellness (as Puffy said)
The Vitality Sensor is Nintendo reaching past the facade of gaming, and into something different, something that could potentially be a great disruptor. But this is all speculation until we see some software.
