There's more to VR though (doesn't mean it will work out, but it may).
3D TV was offering nothing but depth perception, it showed the exact same thing as 2d TV.
With VR there's a new way to interact.
I'm not saying it will take off, I haven't even used it, but I do think there's a chance. With the TV no killer app could even be made, with VR, there's at least potential that someone developes a killer app.
