Haha i don't see Google releasing it this year. But man, I'm excited, if they're getting 2x5500x3000 OLED in a wide FoV headset at 120hz, like they're doing now, with foveated rendering, man ... that's all we need ! Really, it's the end of the looooong 'road to VR'. Looks like the waiting game really might be over in 2019 or 2020.
Pimax is going to be (at least I hope so) a nice 'intermediate' solution but it's still not going to be perfect. This Google initiative is!
