The video makes no claims of how small the tech is, but I agree it's unlikely to be in a consumer package at this stage. The display itself is mainly passive optical components. The input light can come from a single optical fibre from a pocket-sized smartphone-like battery/compute device. Scanning single-optical-fibre projection has been demonstrated by people now at Magic Leap - see the 1mm projection midway down this page: http://gizmodo.com/how-magic-leap-is-secretly-creating-a-new-alternate-rea-1660441103 http://gizmodo.com/how-magic-leap-is-secretly-creating-a-new... Magic Leap have clearly put out mocked-up, offline composited videos before - they are clean, have perfect tracking, and do not use purely additive blending for the virtual content (they look much like Microsoft's HoloLens "live demos"). In both cases I have no doubt those are fake. However this one definitely looks genuine to me - it's got all the hallmarks we'd expect from a scanning light-field display such as described in their patent application - in some frames it's possible to see two frames of virtual content in one frame of the video, suggesting a 60fps refresh of the content. The graphics on show are not beyond the capability of smartphone-type devices, and 3D depth cameras have been available in consumer elecronics since the first Kinect. I'd expect the demos are currently driven by desktop-type PC hardware, but there is nothing on show here that seems unrealistic to me. Of course the watermark in the top right and the text at the bottom was composited afterwards but I'll let them get away with that.
