but hey, the Rev could use a ham sandwhich as a controller for all we know
Who says, if implemented, it would replace the controller?
It could be part of the "interface" Iwata has been proclaiming.
I just imagined a sick possiblity for this technology. Imagine, your playing a Speed boat game, that has a 3/4 top down view. The game is reminiscent of 2D space shooters. Anyway, you use your controller to steer the boat left and right to dodge various things. The graphics are beautifully lush with Nintendo's water making ability being the key attraction.
This is being projected on the floor by the way. Now here comes the crazy part. An Enemy comes into view, but you don't have any guns on the boat. Instead, you step on the Enemies key parts while you dodge whatever it's shooting at you.
That would be crazy fun.
