3D never got to the point VR is at now.
You have Microsoft, Facebook, Google, Samsung, Intel and quite a few others behind it. That never happened with 3D. Plus there are great real world applications for VR not just gaming. So yeah, I think it will catch. What we see now is rough, but second gen should be much better.
Absolute nonsense, 3D was massive and yet it has died a death, just look at just about every TV manufacturer, they had and still just about have a 3D model, nearly every film was released in 3D.
On the gaming front, both AMD and NVidia embraced 3D with NVidia doing dedicated hardware and software and AMD letting a third party (Tridef) deal with it for them. The amount of games that work with 3D is considerably more then what work with VR.
Don't get me wrong I'm not saying that one is better than the other, or that one will outlast the other, both have been around for a long time and have had massive followings that for 3D has dwindled somewhat. Only time will tell how well this generation of VR will do.
One thing to remember is that both of these technologies have been around for at least 50 years, with them getting better and better, but with one massive drawback. People don't like putting stuff on their heads, be it glasses or a headset. once these technologies can work without the headgear, then they might have a chance.
