i used to think that sifo dyas was a misspronnounciation of sidious, but now i think it more likey that palpatine ordered sifodyas to order the clones secretly without telling the jedi, and then killed sifodyas for control of the clones.
lucas did say that the jedi traitor who deleted kamino from the archives is not one that we have SEEN before. Could this be sifo dyas. after all, he was the only jedi to know about the clones
i am the jeditraitor ha ha!
i made my screen name that a couple years ago. after ep 2 it was rumored that the "jedi traitor" was going to be seen in ep 3 and that it was someone new to sw. that ended up being general grievous.
but the general isn't the real traitor, that's count dooku. and anakin can be considered a jedi traitor as well.
