On Thursday 28th August Ebbe Altberg CEO of Linden Lab on Twitter confirmed that official Oculus Rift DK2 support is coming along. There’s still no details yet on when the first implementation will be and I would predict that the public Oculus Viewer will be released in early-mid 2015. Also this week Ebbe Altberg via Twitter said that “SL going to get better and keep going for a long time“. Yay!
Confirmed

I know some people are very anxious to try their DK2s in Second Life / OpenSim so I’ve released this alpha with some very preliminary DK2 support.
