2019 or 2020
By then it probably becomes irrelevant. If it gets to that, I will definitely buy another brand with the latest tech, not Chinese made. The Chinese business style of always over promise by a landslide (90hz, brainwarp(0 info on this since last year) scent module, AIO add on, inside out tracking, eye tracking..... lol pimax is having trouble even getting the hmd done right, I have no hope for them to get all those working in a meaningful timeframe) gets me disappointed as the days go by.
At this point I dont have faith it will even be delivered. I'm not saying it wont be delivered. If it came, great, if not. I'm just going to laugh it off and admit I made a mistake backing kickstarter and get on with life.
At the moment, 2d gaming keeps me quite happy. It's not immersive like vr but it's not a shallow puddle like 97.25% of vr games are. (Except skyrim which is... amazing)
But this is my personal opinion
2019 or 2020. By then I might have purchased something else.
