I'll be surprised if it hits closed beta in 2019. Their development rate is abysmally slow, but that isn't necessarily a bad thing. MMOs are not a fast or cheap enterprise to do right.
It’s currently in prealpha with another round of prealpha testing starting this week and running through December. It’s definitely still a ways off. I would guess 2020 at the earliest. Lot of potential though.
been keeping up with this for a while now. Have a friend who is an artist for VR they just hired alot of people and hopefully will make the process a little faster. But from water cooler talk looking for beta maybe middle of next year and full game 2020. They don't want to rush they want it right. But from all the streams of the lastest prealpha stuff it looks pretty cool.
