2bn users and 100m concurrent users for "SL" by 2018?

Just spotted this in a post about the SLGOGP - the "metaverse" standard for Second Life and SL type virtual worlds:

"2) Scale the Second Life Grid architecture to support the
industry-projected situation in the next 10 years, where virtual worlds
will comprise at least 60 million regions, 2 billion users and in-world
concurrency of 50-100 million residents."
