Its not them becoming canon that make us believe they'll have babies its
A. Kishi loves paralleling NS with his own love life
We've heard that his wife looks like Sakura, that doesn't mean that we should make the conclusion that every little thing that happens with NS happened with Kishi and his wife.
B. Part of the whole message in Naruto is a new generation replacing the old (the whole conversation about "the king" during the Hidan and Kakuzu ac)
So if it's the whole evolution process for a pairing, then why didn't ObiRin have kids after MinaKushi died? I think you and many other people should stop defining this whole surpassing the next generation as some steppingstone for NS to fulfill. One of the main ideas of surpassing the next generation is about the current generation overcoming the mistakes of its predecessors. Like Naruto surpassing all the Hokages, making peace where Jiraiya and Nagato failed in, and other characters becoming stronger than their masters. Now I'm not saying that NS doesn't have a hand in this massage. But the examples that I've listed is how it all started and Kishi wants us to view it as the most important theme in the massage, not NS making two babies so they can surpasses MinaKushi in that regard.
And let's be real here, no character other than Naruto and Sasuke right now has even surpassed Hashirama and Madara. The massage is a flawed so that's why I don't care about it.
C. Kishi confirmed Naruto will eventually have a son
Kishi didn't confirm anything, he simply answered a what if question. Just like he answered if he were to date his female character it would be Hinata. That doesn't mean anything.
