So the current Naruto Gaiden series is about to come to an end. Whether in the next chapter or within the next 11 or so, it definitely has an expiration date on it, which was really already announced before it even began, so it's not much of a surprise.
Rumor has it that Kishimoto's going to start working on a new series in August, or early fall. The big question is - what's he gonna work on? Many speculate it's gonna be something related to his one-shot Mario, but honestly, I don't think so. That short was a really old idea of his that he decided to polish and publish, and that was that.
Personally, I really hope he doesn't steer in the direction of any kind of realism. His work, whether Mario or that Baseball one-shot he did, didn't impress me, and I will always connect his style with fantasy, with feudal Japan and with some kind of adventure plot - so I really hope he goes for something like that in his next series as well. Be it about Samurai, some adventure/discoverer theme (without them being pirates, or else xD) or something else I didn't think of.
The other option is, and I think it's not that unlikely at all, is that he's using this Gaiden interlude as a sort of introduction to Naruto Part III. Honestly, I struggled quite a bit to see how he'd do it, and I still do. I mean with existing power levels being a big hindrance since it feels like those were already maxed out with Kaguya/Madara/Sasuke/Naruto.
I would love to see him doing something like a 10 year time skip though, and only few of the kids still around, with Sarada and Boruto as the protagonists in a crazy, post-apocalyptic world where all the adults were slayed by some uber-powerful enemy - think of Future Trunks' in DBZ, that sorta thing. But really, I don't think Kishimoto would ever go there... unfortunately.
Anyway, you all have any ideas on how he could spin Naruto further? Do you even want him to? And if your answer's a stern 'no', then what kinda series would you like him to create next? Describe it in detail, I love reading everyone ideas.
