This rumor was copied from TheForce.Net
"Darth Sidious has a curved lightsaber. That doesn't mean that the blade is curved. It means that the handle is curved. There are two stories about yoda's lightsaber. One is that it is in his stick. The other is that he has two lightsabers. This sounds realistic to me because on set there were some extras (dressed as Jedi) practicing with two lightsabers. But it is hard to get a fix on cause Yoda is going to be mostly CG. Both Obi Wan and Anakin get their arses kicked by Ducu (sp?) played by Christopher Lee, but Yoda comes out and does some kicking of his own."

Now I dislike the idea that Obi-wan and Anakin could be beaten in combat by somone three times their age. It could happen, but why would Sidious pick a really old guy to be his apprentice? What do you guys think?
