* Google will move into AR space. Probably a simple expansion of google maps to have street view on mobile devices with a transparent rather then preset views. Expect googlemap pins hovering in your view space in the not too distant future.* First use of image based outdoor positioning to give sub-meter position accuracy demonstrated. The race to map cityscapes start.* A merging or two or more AR firms.* Nintendo, Sony and Microsoft *all* show of specific first party new AR applications. (DSi,PSP and Natal based most likely)* A half decent AR dedicated HMD will finally come out, even if its not consumer level.* The first cross-browser cross-platform AR content will start to appear.* AR technology will become a persistent element in at least one major western tv show and will be presented in a fairly realistic manor.* Many sites catalogues AR specific apps and games will start. Possibly even category searches appearing on app shops specifically for them.* The Daily Show will make fun of AR. (and maybe have an interview with a predominant figure in that space)* At least 5 augmented reality outdoor gaming events will be held. Scratch that. Make it 10.and, umm, some hosting of AR content on Wave servers ;)
Again, Thomas was asked for his predictions prior to Google's recent moves, so you'll have to excuse him for the first bullet point.
