OK I did a little research a while back Linden Labs was trying to develop a VR based grid separate from the normal SL Gird. it was called SANSAR. But it was abandoned recently and was sold off to a small company. Here is the news story'
"The game developer behind Second Life has abandoned its grand efforts for a virtual reality follow-up to its early 2000s hit.
SF-based Linden Lab announced today that they’ve sold off assets related to Sansar to a small, little-known company called Wookey Search Technologies, which will take over development of the title. Linden Lab will continue developing and maintaining Second Life and it sounds like some of its employees will be joining Wookey. The deal was reported by Protocol.
The game studio had already announced layoffs last month."
So it seems with the layoff it's basically going down the tubes. Below is the link to the site which still seems to be up.
