I also feel that the Valve team has been working on the non-sexy issues like controls, motion sickness, advanced eye tracking (rumor?), and head tracking as opposed to the narrative that comes out of the Rift which seems to be centered on "OMG RESOLUTION AND FPS!" Obviously, gamers will lean towards the latter but I suspect work on the former will be more important.
I'm also concerned that this stuff will look great, but will require a $2,500 gaming machine to make it all work right. I just upgraded to a Nvidia 950 and from what I've read that's really too weak to do 1080p per eye at 60fps on anything coming close to AAA graphics. I really don't want to be forced to deal with PS3-like polygons and textures for the 3D effect to work correctly.
I guess I'll wait and see. I'm certainly not doing any preorders. I'll let the early adopter crowd figure this stuff out. I'm also waiting for magic leap to produce an AR product, but don't expect that to happen anytime soon. I am somewhat concerned that AR could strangle VR in the cradle.
