Same will probably happen with Occulus Rift, at least to somewhere between 350-400€.
luckily you won't need VR glasses to use mark.space , it's still too expensive at this point.
That's true but for VR to become mainstream the average guy must be able to afford some VR device.
The question is: When would you say it is cheap enough that the average guy can afford it? I mean, a lot of people have smartphones that cost way more than 300€ and still smartphones are mainstream.
You are right about the price. Current vr projects problem is not price. Cables and everything. Also, content is very limited but it is getting more content every day.
Give it 2 years!
