I think many consumer HMD sellers are having this lens problem. Xtal and Varjo are high end B2B manufacturers and ask for steep amounts of money.
Varjo is way, way too expensive to be a concumerproduct.
Xtal might be ok. We'll see what Sebastian has to say in 3 weeks. B2B or B2C? Still high pricerange. Most likely B2B.
StarVR might be just an attempt to be relevant in VR in general. They feel the progress Pimax is making, also the other way around. Have to wait untill tomorrow.
Halfdome (Oculus) is coming in 2019? Their customer service might be OK, its American, but still.
HTC is slowly going to the background of VR. I think. Great work initially, but they are not marketing savvy.
Pimax is still going strong. But has to show something solid soonish. This fall 2018. If it becomes winter in 2018, and Pimax is not released in one way or another, people will wait for something more tangible like the halfdome/santa cruz
