I think it will succeed in long term i don't think even big company like Sony expect an instant success for it

Well, after trying the Google cardboard with my phone Im pretty confident about it this time.  Like seriously, just about ANY horror game can scare you with that thing on your head.  And it is not only to play games. You can actually watch movies in 3D as if you were in the theater.  And lets not even talk about the porn industry.

With as many companies going in on the trend you would imagine there being some sort of market research out there that at least indicates that there could be a lot of interest in VR.

Who knows though, I know people that are really excited by the whole thing, I'm personally more lukewarm but am trying to not project my interest level onto the whole market.

It will be like a thing but not as huge as consoles. Maybe the devices will sell around 15-20 million.

Is going to flop

I don't think it will do very well.

That said, I can definitely see this becoming reality maybe 50-80 years in the future

it will be a short lived fad

Going to be a fad for a few years then start to contract just like with 3D movies in the theaters. It piqued in 2011.

VR is probably going to be successful in the end. But way to the success will be grudgingly slow.

Or, it could die. It doesn't matter what kind of game is in. What matter is how other software will adopt the VR.

VR have unique advantage in that it can create many screens as you want and place it anywhere you pleases. Appeasing to screen space extensive jobs - Like developers - is probably going to be a good strategy.

It's here to stay. It will start off slowly, but will gain popularity at a steady pace as people show it to friends and the tech becomes better and more affordable.

It's not longer headache inducing or thousands of dollars of specialized head gear, it is ready for the masses this time. It won't replace console gaming, just a new form of entertainment next to it.

The comparison to stereoscopic 3D is flawed. That doesn't allow new gaming possibilities and never really had any special games made for it. Yet it always had a steady presence in PC gaming since the 90's. VR can do so much more but will live or die by the software made for it. So far it's looking good, bar some nonsense like streaming xb1 games in a VR theater.
