There are lots of big possibilities for the Sensor and Nintenod says they've got creative ideas(no surprise)what ways do you think this should be used?

Apart from the obvious horror games,why not use it for underwater parts of a game? {I think this is more important than arc/natal,my opinion though people will be paying attention to this and at E3}

They could use it for a new Wii Fit where the Vitality Sensor could tell the player when to stop because they are exhausted.
