2. I think Sasuke will win this one. Him having a change of heart by some dramatic flashback seems most logical. Sure, people will say "this has all been in vain if Sasuke doesn't leave", but he might still leave. I still think he wins though, because Naruto isn't a God and Sasuke's new powers is enough to bring him down I say. I say Sasuke wins and then leaves.

Good first post by the way.
