First came Wii Fit and you canceled your gym membership, but now it looks like Nintendo are set to get rid of doctors as well with their new vitality sensor. This little device was revealed at E3 2009 and it can measure your heart rate (ideally while excercising). Nothing on pricing/release date yet but do you think that this will somehow integrate with Mario Kart? The angrier you are, the faster your kart goes?!
