Yes. But they mean real world regions there, not in-game regions.
In-game the whole game world will exist inside each shard (or 'instance' if you prefer), with a background sim shared by all of them. (IE iron ore demand in Hurston will be the same for all etc).
Each solar system will be hosted by multiple servers (one per planet etc), in their initial plan for 2022.
A key comedy aspect at the moment is that they can’t push the shard player count beyond the server player count for any given location. So the initial player count for the whole shard will be… 50 players
There are various implications: How will they populate a shard with multiple solar systems? How will capital ship battles work? How will they handle transitions between server locations? Etc etc.
Should be fun
