"One of the big challenges of the project is to develop our single-shard cluster technology for network synchronization, that will allow players to freely move and interact in the world without any loading, zoning or restriction. We have started to run our first serious tests with several thousands of players and so far everything works as planned (we keep a linear load increase). So this is looking good, and it is a major achievement.
Do they mean simulated tests? That's the only thing I can think of. I didn't think they had access to several thousand players to test this yet.
