There are a lot of shounen/seinen manga where you can tell that someday the main character is going to fight one of the other characters. Idk if there's a thread like this but....oh well.

I'm bored and pretty interested in which fight everyone's most looking forward to...

I would have to assume most people will choose Naruto vs Sasuke, but for me I expect it too have way too much emotion involved to be very enjoyable.

Personally the fight I'm most looking forward to is Sasaki Kojiro vs Miyamoto Musashi in Vagabond. I already know the outcome, but i expect it to be much better than most fights I've seen in manga. I heard that Inoue was coming back from hiatus and hope it doesn't change.
