3xProjectors = expensive, lamps will cost, they won't last too long even in movie use. Sure you can use just one projector but rez is low then... :music_whistling:
And track ir is still needed, because you have just nice big screen but vertical and horizontal fov is same than in triple screen.
So not worth to get if already own triple screen (IMHO). Bezels are not problem for me.
OR will have widefov about 100-120 degree + 1:1 head tracking and 1440p rez for first consumer version and next gen's even more.
Sure you have to make OC look bad because it's better for your sales.
And rift won't make your vision go bad, there may be motion sickness etc.. .. but it won't harm your vision. Human eye is not so weak. :thumbup:
