Why are people still believing that Naruto can end up with Sakura in canon? They have already given their epilogue and it has clearly stated what happened. I don't see any reason they will change it now. Can you imagine the fallout that will occur after they change canon pairings now? The amount of flak all the staff will get from the NH and SS fanbase. They will literally set fire to the studio if their pairings are withdrawn after being made canon.
They can't tell you about the story because they will get penalized for breaking confidentiality. Even if it is something as obvious as the end pairing.
Not to mention that they have pretty much destroyed NS in these two chapters as much as they destroyed the other pairings in the whole series. That's why every body lost in the end except for the producers and those pairing fans who just wanted the bragging rights.
