very cool idea. It depends on the application. It will be a novelty item for all consumers. Professionals on the other hand, whole different world out there waiting to be conquered: Law Enforcement as in that TV show Continuum comes to mind. Military forces as well with live satellite/drone data piped directly to a soldier's headset provided augmented perception of his surroundings.
Imagine that with Kinect: your hands manipulating what you perceive via your glasses. Hotdamn.
