Not placing any stock in the vitality sensor being game changer. We could see real clever applications of it, but then again, we've had about a year of Motion Plus and it's not like that managed to take the Wii to 50% either.
Personally, I'm inclined to think the sensor will mainly end up being used in conjunction with fitness games to gauge player vitals and cardio fitness over time. Useful, but not something that's going to sell millions more consoles like Wii Fit/Balance Board.
