Umm, dude what are you talking about? Your post makes hardly any sense. Anakin doesn't have a GRUDGE against Mace Windu. Why do you think he killed ANY Jedi...obviously, he turned to the dark side...and joined the Emperor's side and that scene will be the scene deciding his fate...it is almost proven to be a real scene....Samuel L. Jackson made hints about getting to fight Anakin...Why do you think Anakin fought Obi-Wan...not because of a grudge...but because he had turned evil. Even there I'm sure he had grudges against him, he didn't just get pissed at him and fight him...he turned evil and then fought him. Then you also say Mace fights WINDU? Do you even know what your talking about? Windu is Mace's last name. You know nothing about the new Star Wars news...the rumour of Padme cheating with Obiwan is an old one that is NOT going to be used...I don't think you have been hearing ANY Star Wars episode 3 news...Anakin has turned to the dark side, and then Obi-wan confronts him and they fight. Yoda fights with Palpatine because he looks pissed? WHAT???? No, he fights him because Palpatine is evil and he has found that out...Read the Star Wars plot summaries...most of that stuff has been offically proven...as you'll notice the plot summaries are starting to get the right set of events...Read this...It sounds pretty close to what will really happen...and most things in it make sense unlike some of your ideas:

and yes, I know some of you don't like this site...I don't like its layout really, but I thought it was a good plot summary anyway.
