was he created by sidious or has he been around and they just hired him because jango was killed by mace??
to respond to the topic, i was disapointed at first but i still wanna see what he looks like in the movie.we only get to see his face in the picture above...and i'm sure he'll have some great action scenes so i'm fine with how he looks for now.
I don't think so. he would've already found and started taking care of Boba and Durge would have already killed him. Furthermore, in a deleted scene from episode 2, Plo Koon and Ki adi mundi took out a droid control ship, only to realize that it was no longer in control of the armies. So Grievous must have already been in command of the droids by then.
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
