-There are no more Sakura choices?
Sakura only needs to catch Sasuke's hand to save Naruto and kill Sasuke , he will die from shame to be weaker than Sakura.
Seriously , I would like to see Sakura do something else than stab him in the back , take his hand , take Naruto's and make them do the reconciliation seal.
-If beast are alive (I hope they are , if not , IT won't be cancelled and there is 4 humans on Earth) , they could have broken the CT like 1/2Kurama with 8 tails did with Nagato's CT , or the clash of the attacks of Sasuke and Naruto destroyed a good part of the CT or...
They could come help Naruto.
-Naruto escape in some way and make the final tnj while Sasuke is falling out of chakra.
Although it would be "boring" to see another kage bunshin jutsu like in the Madara vs Hashirama fight.
