What's going on with season 4?

I know there is a patreon. From what I understand it's being worked on but it's not a continuation from the cliff hanger in season 3. Can someone confirm? I don't mind that the show goes in a new direction however there needs to be adequate resolution to that ending. Not just "they magically came back" or "it was just a dream". And even if it's going to revolve around new characters, please give the old characters the closure they deserve.
