We're still in preorder phase, aiming to ship most headsets in ~Q2 of 2023.
This is our first foray into hardware, but we already developed a stable Linux VR Desktop (https://github.com/SimulaVR/Simula) from 2017-2021.
We try to provide frequent updates on our hardware engineering progress. For example, here's a recent post showing some videos of our review units: https://simulavr.com/blog/first-glimpse-of-review-units/ If you're interested in community discussion, you might also check out https://hn.algolia.com/?q=simulavr.com.
