So the long awaited update for the multiplayer is hopefully going to be ready "in about a month". That is according to Eric Barone, the creator of the game.
Update on Stardew Valley multiplayer: still making good progress on fixing bugs, if all goes well it should be ready in about a month— ConcernedApe (@ConcernedApe) April 10, 2018
From the questions that was asked on twitter the two main points to take away is the fact that it will be the PC/MAC/Linux first, then Switch then it will come to console. And the other main one is how much will it cost us? The good news there is that it is a free update for anyone who owns the game.
It does seem that most people are getting tired about waiting for the multiplayer release, but overall the comments and feedback is positive and everyone is ready for the multiplayer.
I know I am, now just to see whom I can get to farm with me....
