I agree with you that this is certainly going to happen soon-ish, but 3-5 years is wildly optimistic, particularly when it comes to the Leapmotion/Kinect (which are cool, but a long way away from resulting in realistic 3D interaction) and Google Fiber (only applies if we all move to Kansas City -- I know Google plans to roll this out to other markets, but in 3-5 years I wouldn't expect significant progress, maybe 1 or 2 other metro areas max).
