If you go just on movies, all the Dark Jedi (AKA ""Sith"") are dead, so whose the baddie going to be? I'm guessing newly trained Jedi gone wrong. I'm guessing not Darth Maul's living tissue over a metal endo-skeleton. Edit: Note: The "Darth Plagueis in Episode 7" thread has been merged into this "Who's the Baddie?" thread, for a one-stop thread for all discussion of possible villians in Episode 7.
