Well damn, they keep on having the most unique issues with Steam.
Yes, people are now really mad on the Steam discussion boards that this happened. It's one thing to have it be bought separately from the start, which is still IMO a bad marketing move since they should reward their VR adopters, but it's a completely different gut punch to see you get the thing in your library, get your hopes up that you're being rewarded for supporting the game, and then have it removed from your library, just as your hopes got up.
That is quite a blunder on their part.
I'm still really excited for the game, but they need to be a lot more careful with how they release this version this time around.
