You know what make me rage?
Sasuke tries to kill her two times, rejected her confession and her offer, treated her cold so many times, and the worse part is that, she even realized her feelings for Naruto and acknowleged that he was a way better guy than Sasuke and despite all this Naruto as to be near death for her to realize the obvious?
I think kishi is avoiding an interaction between she and Naruto because Narusaku is already canon it's hinted that her behavior towards Naruto heavily changed when they came back she was more kind and gentle towards him and even smiled on a way that she never did on the series before.
Many mangas do this type of thing, they leave some lingering elements floating around that can take long periods of time before returning to them, look at one peice, one of the biggest story elements is with the void century and rylagh silver knowing about the treasure itself and possibly one piece (the treasure) being linked to the void century. The series has ran over 15 years and still has little revealed on this. I would not be surprised if this is somewhat the same with Naruto and Sakura's relationship.
As for Sasuke's development, yeah he is mellowed out but no reason again to start loving, he never did anything for Sakura, Naruto was there, it would take a great amount of logic for Sakura to still keep loving him and when he redeems himself, she still loves him putting us back to square one, thats not development, thats reducing Sakura to nothing in one entire chapter.
Even in a situation if Sakura encounters mellowed out Sasuke and his crew (taka, orchipedo, and the edo hokages) without Naruto, this would be an intense moment and one in which she would need to overcome Sasuke.
Imagine it like this, if the Ninja allaince retreated from Madara (as I said before) when the ten tails goes into stasis/cocoon mode, during this time (or before it) Sakura and Sai were not on the battlefront because they went to heal the 5 kages. At this site of healing and tsunades fate (betting she dies), Sakura, Sai, and the remaining 4 kages come into contact with Sasuke and Co. First off, Sakura and the kage would need to understand why Orochipedo is there with the 4 hokages, they need to barter some truce because it involved Madara. Sakura's interaction towards Sasuke would be the point of determining her future. Sasuke said he would face Naruto first but among anything tell how Hashirama gave him a thought to do something other than revenge, fighting Naruto is the only way to confirm it. It would be hard to imagine how Sakura will act at this point but even then:
-He still tried to kill her twice
-Its still damaing to her character to love this guy out of pure idealness and stick with it
-Sakura cannot maintain this mentality of idealism towards him or hope that Naruto could simply "condition" him back, Sasuke still did nothing. If Naruto fell for Hinata and then Sasuke started showing affection to Sakura who would still show it towards her, thats just the final straw, Naruto would go down in history with an ultimately wasted opportunity for character development and would ruin Sakura and Sasuke.
No matter how the future interaction goes between Sakura and Sasuke, if naruto is present or not, when Sakura hears the truth about Itachi, how Sasuke is mellowed out and has something other than revenge and promises to face Naruto first for that answer, it ultimately changes nothing, Sakura cannot love the guy who still tried to kill her in open fury, let alone still does not even have her on his list of goals. Sakura is literally nothing to Sasuke, he was a friend at the start but turned all emo-a**hole. I don't see the series ending on a right note between them unless they could just be friends at this point. Not loving, cause Sakura's crush was idealistic and Sasuke has no reason for romance in this story. Its easy as that.
Naruto and Sakura interaction - many reasons and purposes for it, worked both ways even with naruto only taking the romantic intrest.
Sasuke and Sakura interaction - really never made progress, practically in the negative progress zone after Sasuke bolted, tried to kill them at the reunion (but Orochipedo stopped him) and at the 5 kage summit.
I don't see how Sakura should even have her feelings for Sasuke return to simple love after hearing the truth about Itachi and seeing him mellowed out and not doing something revenge based. Sasuke made his choice,
if he never even acted positively to her in the start, always treated her bad, its time to let goSasuSaku is alive in fanfiction land, thats where it belongs, if Sakura still loves Sasuke at the end then this would entire journey would have been worthless on Sakura's point. Sakura needs to overcome Sasuke, if she can then this will make her one of the most memerable characters in any shouen manga, she would have overcome her own inner conflicts when it came to the wellbeing of both Naruto and Sasuke. If she does realize her feelings for Naruto, it would be for all the right reasons, not having a falsified love which is proven to hold her back and even stated by the author himself to be selfish.
Sakura may love the old nicer Sasuke but that does not change the fact of the one who was there for her, if she gains feelings for Naruto beyond friendship, this would come out to be one of the better plot points in the series because it would have been one of her biggest struggles, love who you think you do or who was honest to you and at the same time who she was honest with for a great part of the series. Sakura coming to love Naruto would have been one of the biggest points of the series and would have all the right reasons to occur from all the events between team 7. There is just so much to keep the story intact for Sakura to overcome Sasuke and to become fully developed at least just being over him, she does not need to love Naruto even, just get over Sasuke and the story can still end on a proper note. Just getting over Sasuke and/or loving Naruto would have taken all the issues and conflicts for all characters on team 7 in the right direction and lead to a proper ending. Not just Naruto goes to Hinata and Sakura sticks on Sasuke like crazy glue again.
I don't see how Sakura could simply love him again, 'because he was manipulated and he had his reasons for revenge, and he has a new reason aside from revenge, he mellowed out, I should still love him." I like Sakura and all, but I would honestly stop reading this manga at that point not out of pairing stuff but because even in important opportune moments for development, he again abandons it and keeps things static and weak. Its not development, its regression for the wrong reasons and makes the story overall, dry, state, and redundant. Biggest asspull in manga history. Naruto's love for Sakura has meaning, Sakura's close friendship with Naruto has meaning. SasuSaku has no meaning no matter what way you look at it, its too damaging from this point on no matter how its displayed, no amount of asspulling logic could make up for this, Kishi chose to have Sasuke do what he did, he put Sasuke in that position, Sasuke has no reason for love and Sakura just needs to mature over it, Sasuke is not the one, he is the wrong one.
Naruto is the goal to at least make Sasuke friendly again, but have Sakura turn to him out of everything he did. If anything Naruto is Sakura's best friend aside from Ino and all that more important. Yeah love is f'd up in this universe if she still loves him in the end and Naruto just goes to Hinata, no matter how many times you look at it SS always results in damaged and destroyed character development and plot logic.
