I DO believe we'll die!
there is just no future for him, his only option i to continue being a terrorist. He can't be forgiven, at least I don't see it happening.
BUT there is another reason I think he'll die:
He'll get the Rinnegan! WHY:
the only reason kishi made the rinnegan the next after EMS is to that Sasuke can unlock it!
Madara doesn't really need it, kishi could've made Perfect Susanoo just s EMS tech, and besides Madara hasn't really used it in a was he couldn't have managed with a Susanoo..
+ the main story is about Naruto and Sasuke
So the only reason Madara has Rinnegan i so Sasuke would awaken it..
AND why'd Sasuke need Rinnegan???:
Again if kishi wanted he could've made Perfect Susanoo a EMS tech, so Sasuke could battle Naruto i EMS mode..
The only thing I can think that as for the plot, for Sasuke to have the Rinnegan i to use Rinne Tensei, to bring someone back to life.
Most probably Naruto will die and Sasuke with plot no jutsu will decide to bring him back to life.
----> kishi's done it a lot of times with:
Gaara
everybody from konoha, when pain invaded
after that Edo tensei and etc.
He likes bringing people back to life for the cost of another's
And it would be kinda epic to see Naruto die, and Sasuke sacrificing himself to bring Naruto back..
It would make sasuke one of the good guys, and to find forgiveness, and is I think a far better ending for him than being killed by Naruto and being seen as weak and a bag character.
