I think it'd be pretty sad if this was the end of the fight already. In my perfect world, Sasuke's chidori would end up getting crushed by the rasengan, but then Sasuke would open the curse seal, and beat down on Naruto, then Naruto would open up the Kyuubi over Sasuke's total betrayal of the leaf village, and just because we can't have Naruto die, and then Sasuke would open up the 2nd seal. In this perfect world of MINE, Sasuke would lose. Of course, we all know that if my idea came about, 2nd form sasuke would win because otherwise this entire arc would've been pointless. And we can't have that.
