Hello Games is teasing out No Man's Sky Beyond, the next major step forward for the game. Sean Murray said that Beyond will make big changes to the game in the same way that the Next content expansion did in summer 2018. Most notably, Murray wrote about "No Man's Sky Online", though he did say that NMS is not an MMO but that it will feature "a radical new social and multiplayer experience which empowers players everywhere in the universe to meet and play together".
"We will talk more about each of the three major components of Beyond when we know we can be precise and look forward to sharing more in the coming weeks." Murray wrote.
No Man's Sky Beyond is planned for Summer 2019.
