I HAVE FIGURED IT OUT!lucas's orignal trilogy of trilogies was anakins's fall in part one, the rise of luke and defeat of vader in part two and part three would have seen him fight the emperor and find the other force user and pass on what he had learned. now the common held theory is that Lucas was so burned out by ROTJ that he decided to kill the emperor in ep 6 and be finished. however in ROTS palpatine siad that he and anakin could work together to discover the secret of eternal life. how do we know that they did not succedd? maybe that is why anakin appears as a ghost the end of ROTJ because he and palps had discovered the same method as QuiGON. So my theory is that palpatine will indeed return in the new trilogy possible as a ghost and he will try to ressurect himself. What you guys think?.
