That would be a terrible outcome, seeing as I said before he hasn't shown any sealing capability or the ability to use Mokuton. We also don't know that Ashura had Mokuton. It could be a very rare Kekkei Genkai, like the Shikotsumyaku.
Sasuke being able to use Preta Path isn't hard to accept. Nagato and Madara were able to use it. It's a Rinnegan ability.
Did he not re-seal Kurama after gaining his chakra earlier in the war?
He has the key to the seal. He can open and close it whenever.
maybe naruto use flying thunder god to escape sasuke's chidori...
Naruto lifts his head and has Itachi's MS Sasuke looks shocked and it reveals that everything been a genjutsu since Itachi vs Sasuke.......
Occam's razor
Naruto probably catches the chidori with his Right hand, uniting the Rikudo seal with Sasuke's seal on his Left hand
ending Tsukiyomi and explaining the bandages on his new character design
Yes this is true. Most likely naruto will TnJ sasuke because naruto needs sasuke rinnegan to undo IT unless naruto takes sasuke's eye but that won't happen because sasuke is shown with the rinnegan in the movie sketches.The S06P explained that the way to undo IT is to have both the Rinnegan and the Biju Chakra that resides inside Naruto together forming the Rat Seal in order to undo IT not with the Clash of Seals like was predicted a while back

Even if sasuke realizes he's weaker, he'd still would want to kill him. Naruto has to make him see that his ideals are wrong. Something like that...Yup but it's hard to see something like that happening with only two chapter's remaining though it's still very possible but I think the only way TNJ will work if Naruto makes Sasuke accept he's stronger then he is if TNJ is to work
