Alright here are a few things I thought about that probably wont be true but what I think might happen
Itachi went to stop the Edo tensin but even though he broke free from being controlled he is still dead. That might mean that when Itachi kills Kabuto he will probably die again.
Heres a little idea I have on what could happen with Sasuke and Tobi.
Naruto and sasuke fight and both are really beat up and dying so as what may happen Sakura must choose to save someone and chooses to save Naruto. Sasuke then says to sakura (this probably wont happen) to give naruto his eyes. Naruto is revived but still hurt then Tobi goes and grabs him.
Naruto is killed with Kurama being removed and Guy Kakashi and Sakura go to help him but its to late. Guy says to Kakashi and Sakura to take Naruto and he will halt Tobi (Guy goes 8th gate) Sakura and Kakashi make it out and Sakura decides to revive Naruto (Maybe Chiyo tells her how)
Sakura dies and When Naruto is revived see Ssakura and maybe gets rinnegan from his loss. Naruto confronts Tobi who has the 10 tails but Naruto befriended them so maybe they disobey Tobi's Sharigan and Listen to Naruto. Naruto then fights Tobi without the tailed beasts using his own power to defeat Tobi.
This is a rough Idea there are probably things that wont make sense and wouldn't work but still hope you like some of them
