Well this is my predictions.
Naruto and Sasuke starts out fighting and the others(that was caught in the shinju tree and didnt know about their powers up) and cant believ their eyes seeing how fast Sasuke and naruto at moving while fighting easier(with taijutsu for a while) and the black rods.
Then they will start out with jutsus and in the end with the big forms susano and narutos bijuu form.
Then probly both fall down exausted and no winner
