What do you folks think woulda happened if Anakin hadn't turned to the Dark side and instead let Mace Windu kill Sidious? Do you think Sidious would really have died?
Nah, just UNLIMITED POWAR a bit sooner methinks.
Though, Terran Frakking Command said that when he played Mace Windu, he thought Mace Windu genuinely defeated Palpatine during that duel, just that Palpatine was relying soley on Anakin's betrayal. But that's just Terran Frakking Command, isn't it?
(ie JABBA THE HUTS SON HAS BEEN KIDNAPPED! wowsa!)
Then that's another inconsistency that appears due to Lucas' negligence of the already established Expanded Universe: Jabba the Hutt was smuggling cortosis (lightsaber resistant metal) to the Separatists. At the same time, apparently he was trying to stop Gardola the Hutt who was also supplying the Separatists. And now his son (who mysteriously appears out of the blue) has been kidnapped.
