He will be in the final movie for the final fight. Sasuke has redeemed himself, especially he's the one will deactivate IT with his Rinnegan. Haters like Uzmakimadara are just bashing like always with illogical reasons. Konoha did Sasuke wrong. He was an innocent, sweet, caring boy who lost everything. Itachi even admitted that he was at fault for turning Sasuke into a criminal.

if Sasuke dies then the conclusion of this story is ruined, and there will never be balance. The Sage will never have closure. He chose Ashura, creating a war between his sons and their ancestors. I believe Sasuke and Naruto will rule together in the end, and the cycle of hatred will be destroyed. After all, Naruto is Yang and Sasuke is Yin. Without one, there will never be balance nor peace.
