With everything that happened this chapter its an interesting aspect that can go both ways, now that obito is standing, he is the only one who can really impede the efforts of madara. Will he stand or fall down instantly next chapter? Its funny how his sharigan is strong enough to hold even zetsu against his own will. Well it makes sense to have zetsu on him because zetsu is the only thing keeping him alive.
So for anything else that can come next, the prospect of naruto's recovery is likely still on Yin kurama, given if something either weakens madara a bit, seals him, or obito manages to pass yin kurama to the others, then naruto is saved, otherwise its a tug of war next chapter. We could assume Obito can put up a small fight but not enough to face madara himself, thats what naruto and sasuke are to do. I know some people have thought the fruit is still out there, it may be but nothing until otherwise seen or hinted at least. I know some people have compared sakura to kaguya, but i really always expected kushina to be closer in this aspect like how many are going on with the same ideal linkup between naruto and the sage. As for Sakura, well yes its true the final panel of the notion the promise obito mentions could be brought up, I mean it was the unexpected small thing this chapter I will say. We knew something about Obito's last act or redeeming himself but not how he would do it, what would he do, or what would he say. I do find it satisfying that zetsu was going ha ha last chapter, now he is stuck in the place he doesn't want to be.
For Naruto's recovery though, its more towards the yin kurama retrevial situaiton, but if the pots are still a factor then its either kishi could show more drama (obito gets knocked down, loses yin kurama but still does somehting to succeed then perhaps the brothers event is still possible), if the pots are empty then maybe its sealing madara temporary or at least weaken him to the point he is sealable and his power suppressed (i can live with the latter, long as we have a good actual battle unlike bleach with anticlimatic aizen espcially considering madara just dropped the tools). Otherwise if it was for humor then kishi was bored and wanted to bash gai and lee on the head for no good reason other then saying this is how those 2 minor characters (samui and her brother) come back. Likewise not really happy on minato's luck, I mean its been bad, but i wonder if the strike was permanent or just long temporary. Really I am leaning more on this being the start of the recovery, I doubt kishi would give madara another quick he wins no matter what chapter unless he knocks obito over quickly, really i just see obito being the frontrunner of this fight to weaken madara a bit so naruto and sasuke recover in time to prevent the eye of the moon plan. Basically a last second save and then they fight. Considering the curious event of Sakura hearing Obito mention that promise to rin, it does lead to some potential and curious interaction, if anything if its supposed to be about naruto surviving, it could be that next chapter or so theres a chance of a naruto/sakura-obito/rin link but in this case, obito stating how naruto will succeed, basically for all this talk of roads, obito having come to his realization and pulled his own darth vader event, basically in regards to the sakura stuff, my best estimate is something about how naruto told me about his road, my road was different, but i can at least cross ahead into his and reopen it for him, by ending my road, i will allow naruto to continue down his and people like you (referring to Sakura, Gaara, Kakashi, etc) that are to help ensure he moves forward and help him if he falls as he leads them. Thats the best guess I can give. But I think its safe to say the sakura sacrifice stuff is ending, its more likely Yin Kurama will get to Naruto and Obito will sacrifice himself so naruto can continue, I hope I was at least right about obito sacificing himself for naruto because after seeing this chapter and the curious end stuff with the promise he mentioned, it is fully appropriate now. I just want to see how this fans out I mean madara is still a god and obito is more like a fallen severly weaknend demi-god so obito most likely won't last long, but if the wound was enough to stop madara for a bit, thats fine by me, hell if obito took out the senitient clone of hashirama, giving that clones face a good punch in like master chief did to a flood assimulated captain keyes (you who played the game know what I mean) then that would be neat, take away his sage power or at least healing, he is no longer OP.
