Saw in the Nintendo Direct that they are bringing that panorama-view videos where you can move the gamepad around and see any view of the video (flock of birds flying I believe was one of the videos). They will cost money but they are going to offer the first one or so for free. That is a more interesting feature (panorama view) than watching old tech demos (or at least have the tech demos display panorama view).
