1. Will not happen
2. Will happen
Do you think it'll happen? I don't think so for 2 reasons: The story is coming to a close very, very shortly so there not be time for it and having them fight would continue the cycle of hatred for the Uchiha and the fighting would never stop, thus making the whole Naruto story pointless.
But I also think it may happen because I believe Sasuke's desire to get rid of the Bijuu will interfere with what Naruto's desire to be friends with them.
