My initial response was, nintendo is smoking crack, but after a few mins of thinking I realized that this could be be the most revolutionary way to play games, I can't wait. Just imagine swinging the bat in a baseball game in stead of pressing a button, or using a sword your way, not the way that it was programmed to be used, this controller is revolutionary in alot of ways, people need to think outside the box for a second instead of bashing it.
The only thing that concerns is is the rev powerful enough to really make this controller design look revolutionary, like I said you can slice a person with a sword your way, in stead a it being programmed, but that will require alot of extra animation can nintendo pull this off? we will have to wait and see, at least they are using DVD so there should be enough space to add say 50-100 free animations to a sword, and make it look like you are swing it the way you use the controller. If they don't add new animation and just make you swing the controller around to a programmed animation, then the controller won't be revolutionary, it will just make you look like a mad person swinging his remote around.
PS: One thing you can say about it, you will lose wait or strengthen you jerk off hand.
