The best way to predict the future is to create it.
Re: Why bleach isn't back yet?
I still want them to animate the last arc. The beginning of the war was totally awesome. I really want to see Yamamoto vs Bach fight in animation. Though, it won't be the same without Yamamoto's original voice actor.
I think they will animate last arc, it seems to be pretty popular it has a 12o'clock time spot on toonami every saturday. Naruto is after bleach so maybe bleach had better ratings?
It dropped off in Japan. The fillers were too random, like Franken Ichigo. However, the Dub is just now getting to the Fullbringer arc. So if the manga ends in a year or two then the anime might get the Inuyasha treatment.
Fillers really can't be blamed, Naruto has fillers at random points too.
It's because it was too close to the manga, they'd rather complete the last arc with no breaks/fillers.
Once the manga is finished, the anime should make a return after a few months.
The Anime was axed in Japan because of all the fillers for a start and because it was getting too close to the Manga, among other reasons. Which reason is the correct one, however, no-one knows. Maybe once the Manga is completed, they'll do a reboot. But I'm pretty satisfied with the Manga. I don't like Bleach's fillers. They're lame.
