Aside from chidori and Lee's fighting style, Sasuke has not demonstrated the ability to copy jutsus yet. Even with those two instances, we don't know how long it took for him to actually get the moves right (up to 1 month). I don't think his eyes are developed enough to do anything cool yet.

I agree that a fight between Neji and Kimimaru would be cool. Or at least Hiashi vs Kimi. Kimi's kicking of Naruto's ass is no cooler than Neji's during episodes 60-61. Naruto's just too dumb, slow, and uncoordinated.

If there weren't half a dozen people spoiling about how cool Kimimaru is, and how he's going to bust out some ownage later, I would be more concerned about Sasuke coming out of the barrel. As it is, bleh.
