In my opinion, although she won't physically make an appearance, Isolde will definitely be mentioned. Mordred or Morgana would persuade Tristan and ask him to betray Arthur and they would bring his dear Isolde back to life. Then Tristan would think about betraying Arthur but would ultimately remain loyal to him, thinking that Isolde wouldn't never want something like that. And then maybe that would cost him his life, who knows...At least that's what I think should happen!
