It has the potential, but it is still so hampered by the physical constraints. You look like an idiot, you're not very comfortable, performance is meh, battery life is horrible and you need ample space to play in.
Even if all of this was fixed tomorrow, many people have been burnt by previous generations, and don't have much hype left for VR. I've mothballed my Go, my friends sold their Rifts. Fun as a gimmick but as a main gaming/media platform unthinkable.
While I agree that it's probably inevitable that it will become a staple device like a smartphone is today, I wouldn't hold my breath.
