That would definitely be awesome. The problem is that you are going to puke your guts out. I've never seen ARMA 3 run at a high and solid framerate.

I don't think that VR is a fad, but I do think that it is a niche and will stay a niche for a long time because of the price and other limitations.
AR is cool, but really hard to display properly. There's a reason why jet pilot helmets cost so much. I'm bit sad that Google abandoned Google Glass though.
