I was hoping that Google Glass will be the next de-facto device/platform which everyone will be using. Feeling so sad a great idea didn't work well. Maybe it was way ahead of time and can be relaunched again.
Likely will happen at some point. It's the next logical extension of consumer devices after the smart phone. It will happen eventually, except there isn't a clear time table as to when. The concept is general purpose enough that interesting things can be done with it.
