what the hell I can't get that link to work...
Though, they did have an interesting article on what the revolution controller's big feature is...
"tilt feedback" apparently taking our current rumble feedback a step further by being able to apparently force the controller to apply rotational force.
That's kind of cool if it's true but I'd hardly call it "revolutionary". Especially when you consider the kinds of games you play on a nintendo system... they aren't really known for their Racing or FPS games (imo the two genre's that could utilize it the most)
