Hardly a huge step forwards
I already have a 3D headmount display and have done for about 4 years now. I hope that "evolved enough to deploy" means they've made some serious advances over the prototype kit at CES as the only technical differences I could see between that and my ageing headset are that it uses OLED screens instead of backlit LCD and has a horizontal resolution of 1280 instead of 1024. Slapping a white plastic surround on it is hardly enough to make it next gen kit. The hardware was never the issue here, it was getting proper support for it into the software.
