Eh all I know is, Sakura is here to stay no matter what, even if she should die temporary.
Heck stuff I saw eariler just made all the more sense, like if Tsunade dies, Sakura won't even be impacted by that.
Again if we see Sakura focused on Naruto, like if he was the sole reason she became stronger for this new power, then how much has Sakura actually done towards Naruto now?
If anything I'm betting the thing to make her turn will be the Naruto vs. Sasuke fight, hell its as I said many times already, NS has everything laid out, it has the direct foundation now with the Sakura-Kushina parallel. It can come in so many ways and still work.
Also funny to see a poll for people wanting their pairing. 
Funny how people even think stuff like this would actually exist, its like asking people if they want to spoil the ending already. Can you think of any long running graphic novel, comic, or manga series that actually let the fans choose the overall ending to the series? No didn't think so. Kishi and his authors are not going to bend over backwards for fans like this.
If next chapter reveals Sakura's power and that she gained it because of Naruto, Kurama poking fun at Naruto for the girlfriend comment, hell what if Kurama reveals Naruto still loving Sakura or makes some remark about her temper too? Geez NS is not canon, but theres still so much more than can slowly invoke it towards the reader.
