Anakin and Dooku's fight!
Has anyone else noticed that when Dooku and Anakin duel, after Dooku knocks Obi-Wan to the ground, Count Dooku and Anakin have exactly the same fighting style? All their moves are the same, with that saber-over-head stance and everything. Could this be a reference to Anakin's future place in the next film, instead of Dooku?
It's just a minor thing, but quite noticeable.
