Dooku won't live long enough to fight Windu. He's gonna die, and die early at Anakin's hand.
But what I wanted was something like this:
Dooku has Palpatine kidnapped right? so windu goes to get him and is confronted by dooku, the 2 battle, and then anakin shows up, dooku finishes off windu, and it pisses anakin off, and then palpatine tells Anakin to like let it all out (like the emperor telling luke when he fought vader), and he goes all out in rage and anger, and kills dooku, giviing to hate and all that junk, so it mirros the same in RoTJ, with the difference that ANaking goas all out, while Luke stopped.
Altough that won't happen, that's how I wanted it to go down.
