I hope they can make the events of KOTOR and KOTOR II canon (forget the Old Republic stuff). Those two games are among the best of Star Wars stories.
They would make for an awesome 4-movie series.
Yeah that really would be awesome! It would be great to see Darth Revan as canon again, because he is such an awesome Sith. Although, in Rebels, people have theorized that the Sith Holocron's voice is that of Darth Kraya from KOTOR II.
