1. There's a fully produced short-film called The Crossing and that reveals what happened to Elizabeth Shaw (Noomi Rapace) and the synthetic David (Michael Fassbender) immediately after the events of Prometheus. It bridges the two films and is much better opening that what we got in the Covenant film.
2. Director Ridley Scott revealed in an interview that the next film is called Alien: Awakening and it takes place between Prometheus and Covenant. Oh, boy. Here we go again with what might be the first ever prequel sequel prequel.
