And instead of elaborating, you are sidestepping and saying forget it again. If I miss a point, clarify. What exactly does it do in the demo that it hasn't done to some extent?

My point is, that the E3 2011 trailer showed us a Nintendo tablet and what we got was a Nintendo console with a controller including a screen.
