From the article:
"The instancing means that you’ll never run into more than a few dozen players at any given moment, as that’s the upper limit on the number of players that can be in any given instance. You’ll never find yourself parked outside of Lave Station watching a thousand players shuttle in and out of the docking bay—there might be a thousand players at Lave at the moment, but only a handful will be in your instance with you."
I wonder whether the 'new way to interact with the galaxy' trailed for 1.3 in last week's dev update would be some more artful hiding of the 16-32 player instance limit, like, for example, somehow giving an abstracted view of real player volumes either on the galaxy map or in Supercruise? At the moment we only have the Community Goal stats and the traffic reports to see in-game how many players are active in a system.
