Please review blogger Inara Pey's post for an excellent compilation of currently known public facts about the new Sansar Project here: http://modemworld.me/2015/07/25/the-sansar-summary-july-2015/
This is the best summary I've seen so for of pubic information that's been released and well worth a read if you have an interest (as we all should) in the new Linden Lab Sansar Project. She cites her sources and everything for a good comprehensive picture of what we might come to expect.
Here is another RL recent media report: http://variety.com/2015/digital/news/second-life-maker-linden-lab-wants-to-build-the-wordpress-of-virtual-reality-1201546110/
