I think their next add-on should be an electro-shock machine. Lets go one step beyond rumble, and physically electrocute the player.
Then we can combine the two, and have a game where you have to remain calm while your Wii is trash talking you, and electrocuting you. Good for anger management classes.
In all seriousness though, while an odd choice, there certainly is some good (if highly specific) gameplay potential in this. I suppose it might be more of a Japanese thing, with their whole blood type personality thing. All that being said, if Nintendo can make a game that does a good job of relaxing you, I'd be damn happy, I always feel on edge. :)
