As far as the hardware goes, a lot of this stuff is already out there in different forms: Epson Moverio, Vuzix (as shown in this demo, ...), albiet not in the form factor that would allow for mass market penetration. That's where Google, and hopefully Apple & Microsoft, will do well and allow for the app makers to come in and add value.

That being said, there are still a great deal of Computer Vision problems that will need to be solved to successfully implement "Strong AR". The video was a nice proof of concept, but that's what the Google video was too.
