That'll depend on A: If he has a willingness to actually undo the ending. And B: If his editors don't hound him. The apparent lack of editors working on Boruto since its serialization as Bail reported may mean that he could potentially insert a plot-device like I.T. in the manga withou disruption, but that all depends on if he wants to at this point. Again, I'll wait for summaries to see what he'll actually do, but I honestly doubt he'll go that far as all of the gaslighting he's done since Naruto's conclusion in interviews and the like.
I'd say don't hold your horses guys.
I don't think he ever wants to get his hands dirty with pairing drama so I think he'll avoid it at all costs.
At most, what he'll do he'll target SasuNaru fanbase, like he did with the Boruto movie.
But NaruSaku? I don't think he'll ever return to make it happen...
Especially since the old fanbase has moved on to better things.
Yes, exactly. There's such little chance of that happening that it's a bit more likely, if he were to go down that route, that he'd do it after Boruto.
Forget IT, honestly. It wouldn't achieve anything. Amongst many other things, he would have to bring Neji back due to the reason why he died, so a potential do-over would have to start from 600 for it to mean anything. He would also have to come out and say that all of this was not his intentions and name the guilty (SP, Shueisha, rotten editors, himself just giving up etc.)...which they might take offence too. Unless they're in on it for the money and are willing to take the hit, I can't imagine it happening. Oh, and like you mentioned, let's not forget about the extremely contradicting interviews he gave that sounded like he was reading a teleprompter from SP themselves. I can imagine invalidating those would be relatively easy given how disgustingly false they were.
Let's say in theory he did go down this path in the future. I would hope that it creates a precedent for others to not fall down to the same fate, popular or not. To take care of their mental health. Highlighting problems within the industry could either backfire or start a well needed conversation.
BoltXSalad (which to them is NS 2.0, doesn't matter what we think to them so don't have a conniption over it) is the only pairing that's going to happen in this manga. Remember Samurai 8 where he spent 10 chapters going "I'm not switching love interest again." That's not, "I shall restore Sakura as the love interest when I get the chance." That's, "I don't want to deal with pairing conflicts or editors forcing me to change the story/pairing to please one group, again."
Sakura existed to please his wife after a certain point. They had move past the feud the ending caused already. Bringing up NS again would just lead to old wound being reopened.
NS would only happen as a last desperate ploy especially since he's now required to write the sequel.
Oh, when Naruto dies he going to have final words for Bolt (father-son) Nail (role model) and Sasuke (not gay brotherly moments of not gay). At worse even if he is spiteful he might have Naruto say he always wanted to kiss her cute forehead. They will likely all assume he means his wife while Sasuke wonders if he was talking about his wife. That's it.
sooo, which one of y'all getting me that celebratory drink when what I say comes true? I'll take a celebratory cake and 50 push-ups from you Bail. =D
