I find it highly unlikely. The game struggles to even save and restore its state correctly (sprinkler, main PC, glowsticks until recently, etc). And you want it to share this state accross network? Plus a lot of things are dependent on player’s proximity and PoV, which is demonstrated by new videocamera item (you can fil walking mannequins, for example). Such events would need to be entirely rewritten.
Maybe eventually someone makes a multiplayer mod, like it happend to Subnautica, but I really don’t think we will be getting multiplayer in the base game.
