Glass seems like it's far away from becoming a HUD. From my understanding, it's essentially just a mini-screen in your peripheral vision. (This is also a big complaint I have of Google Glass. I don't think I've ever actually seen a single image from Google talking about how it looks from a wearer's point of view.) http://i.ytimg.com/vi/d-y3bEjEVV8/maxresdefault.jpg http://i.ytimg.com/vi/d-y3bEjEVV8/maxresdefault.jpg Is the type of pictures I typically see. This is portion of your vision blocked by a semi-transparent area so it can reflect the very small and basic text projection. When I think of HUD, I think of something that is able to overlay my vision like so: http://www.niemanlab.org/images/behavio_hud.png http://www.niemanlab.org/images/behavio_hud.png (Just first image in google search) Since neural manipulation or a screen being able to be on a contact lens are probably far away technology wise, that essentially leaves us with having to create something that can either draw or project a screen on a normal pair of glasses. Once you can wear a prescription or prescription-less pair of fairly normal looking glasses that can draw/display image/shapes/text/color anywhere on the lens, then I think the actual "revolution" will take place and everyone will quickly buy and use them constantly.
