Just for fun, we could have a contest to see who comes closest to guessing the actual release date. Maybe VR could come up with an award for the winner(I'm not holding my breath). My prediction is March 14, 2021. With several more pre-alphas to go, that should take us through 2019. Alpha and beta should take at least a year to get through both. I hope release day is sooner, but I just don't see it happening.
