They don't actually draw the manga weekly. Kishi is also an artist, and as a artist, He's always drawing.^This expresses my thoughts. Why do you all get so annoyed if Kishimoto-sensei takes a break for one week? It's just one week, you're not going to die from that.
If you actually took the time to study the Japanese culture, you would learn that they don't get a lot of breaks. And mangaka is one of the most hectic jobs if you ask me. Especially if you have to deliver your work weekly.
But as far as I know, there are no breaks scheduled.
And if there were, so what? It would only be one week then :sy:
Let Naruto fans be Naruto fans. If fans are eager about the next chapter? Is that not a good thing?
