i think nvidia's headset(i assume they are making one??) will probably be locked to their gpu's, or like to get all the features you need a nvidia card, i doubt very much they will lock out other headsets from running on their cards tho
maybe the 1st ones wont be that good anyway, pretty tough thing to get right
i might be as old as u by the time they get it right
Tomorrow night is where we find out what is what and I am quite intrigued, as it is supposed to come with the Tegra X1 built in if the sources are correct. That could make it pretty mobile but doesn't fill me with confidence for running high end, high res games.
