Know why its funny we don't need to worry about sasuke?
-His situation isn't as severe even with the mysterious man, its most likely to save him, i doubt the guy is there to stab sasuke unless its like what kishi did with black zetsu.
- He is kishis favorite character, he has gotten a lot of free passes. I wouldn't be surprised if this one was one as well.
We are concerned about naruto's situation because face it, he is almost in the same situation as gaara, though a jinchurki can be revived, we are hoping to see if there is actually something that can be done thats non-jutsu revival related, aka getting yin kurama or at least the brothers chakra into naruto. Really the situation would be the same if someone sacrificed themselves to revive naruto like chiyo did on gaara, but part of the curiousity of this part is we get a unique situation of there actually being a way to survive the extraction (not counting the ten tails extraction) kinda like how people previously thought edo tensei was unbreakable, well someone with advanced natures can either increase the time it takes for them to recover (on hiruzen) and even outright obliterate them to nothingness (minatos arm, if things go down the brothers route, I suspect madara will get rid of the brothers like this, well after the energy has been taken if things go this way).
Again I don't see sakura sacrificing herself just due to story reasons and well no real notification of her having chiyos technique, if anything I'm again leaning more on the stuff with the pots and what the sage said about them all the tailed beasts being one again someday and well this time, all 9 tailed beasts are in madara, only Yin Kurama remains outside. Really it also depends just on what occurs with Black zetsu at this point I mean if possible, Black Zetsu could always be overloaded not realizing this is something all jinchurki ran a risk with.
Then theres also how Madara decides to handle the situation I mean he would most likely turn his back on kakashi, minato, and gaara going right for obito/black zetsu to get that rinnegan. I mean again, i'm thinking he would most likely ignore naruto given his condition and sakura for well, one part its she needs to keep him breathing for now and the other well, he just wouldn't care thinking its pathetic to see her try.
Well we will get more rigid answers next chapter, until we see what madara does and how things unfold in the yin kurama situation and what happens with the pot and gourd, then we should find our answers. All I'm saying is, its better to focus on the stuff we actually see in front right now before assuming the things possibly in the back, upfront we have 2 things for naruto's recovery, yin kurama and the pots (provided the brothers or energy at least is in them) if yin kurama isnt able to be saved or the pots really are empty, then its likely to be something sacrificed, but even then if it was sakura, she could only go temporarily otherwise, well if she was gone for good, it would be a mess. I mean we know how important sakura is to the story, she needs to surpass tsunade, there needs to be resolution with her character regarding naruto and sasuke, in this situation she doesn't get that resolution with sasuke (not speaking for SS but yeah this would need to occur like Hinata's with Naruto) team 7 needs that happy ending. But in my eyes, the stuff upfront offers more potential and dismisses the actual need of a sacrifice. There can always be a sudden reveal but its more likely the solution to naruto's recovery is either Yin Kurama or the brothers.
