What's this about the new commercial about the Last that confirms Narusaku? It talks about Sakura. Some people think it suggests that NS have a son.
I think that they wanted to say that Sakura became a beautiful woman because she's with Naruto.
A girl is always more feminin when she's with a guy. And that's also what Tsunade was trying to say to Jiraiya about Kushina, that she became a beauitiful woman when she was with Minato.
Or, maybe they try to say that Naruto is lucky to be with such a beauty like Sakura?
But I prefer the first one, it would be a great parallel (again) with Kushina.
I really think that NS might be canon already in this movie.
About Naruto's son, he didn't confirm anything, the interviewer just wanted to know IF he had a son, wich name he would give him.
Sakura doesn't seem to be pregnant in the movie, so no son.
