The Bleach Manga has entered what was labeled as the final arc (The Thousand Year Blood War iirc) so idk what is going to happen. Presumably a second series like Naruto: Shippuuden will cover that arc once it has some time to progress, but that will probably be the end of both the manga and the anime.
9 years of anime...Tite Kubo has done well for himself. I'd imagine he's either ending the story out of getting tired of it or fear that it would develop Dragonball Z syndrome where characters strengths become so ridiculous it practically undermines the original story (as if it wasn't almost treading that ground already). This is just presumption though, who knows, with such a successful series in as well established a setting as the bleach universe, it's very possible we could either get a spinoff or a sequel series.
