maybe he'll reverse-reverse summoning and send them both into the frog mountain, in order to protect the village!
it'll be just like that other show!

no jokes, though, I really want to see Naruto joining forces with someone new, maybe Kisame and Killerbee, maybe Madare will release him from payne in order to play both sasuke and naruto in order to fulfill his devilish Uchiha creepy wishes.
