Was Dooku planning to betray Sidious?
In Episode II when Obi-Wan has been captured and is locked inside a ray shield, Count Dooku explains to him that Darth Sidious is in control of the Separadists and the Republic. He says "Join me and we can end the Sith...". Is Dooku being genuine? Does he actually want to kill Sidious and the remiaining Sith? Or is it just a decoy of some sort to kill Obi-Wan?
