Re: Bleach may continue from next week(Here is a proof):)
It's Studio Pierrot decision. Stopping an Anime abruptly; despite the storyline forwarding in manga; due to inside-reasons/policies of a Studio is no new thing.
Sure, they left the future of Bleach Anime a bit darkened, so there's glimpse of hope. But sample this - Gintama', Beelzebub and now Bleach have both been ended by Studio Pierrot. Despite no official statement about their financial condition, you don't have to be Sherlock to guess that there is a certain glitch.
Here's my take on the situation:
They had to end some series animations for reasons known to them. Now, while it's irrevocable decision for Gintama and Beelzebub since they officially announced its End. They'll surely concentrate on some Series only with Naruto Shippuden being the sole flag-raiser of the Studio. Perhaps the Studio can't afford the continuity of both heavy guns - Bleach and Naruto.
This situation reminds me of Studio Gallop situation - who ended Eyeshield21 Anime despite a good chunk of following and popularity and that manga was ongoing. The Anime was given an end due to financial reasons and the storyline continuation in the manga was never shown. They also concentrated on a single series there-after which was Yugioh franchise series.
In case, Bleach final Arc in manga achieve immense success, they might actually return - declaring this Ending to be a Hiatus - and continue the series. I think, they'll continue the Animation of the Bleach Series only if they're certain that the last Season achieve Huge success and be a complete money minter.
Perhaps, they were losing some fan-following or money recently. It's a money affair. Another bad thing for those hoping a continuation is that the Bleach Manga has been on a downhill slope in terms of sales and that surely isn't inspiring for a Studio who clearly seems to be having problems in my eyes.
I just hope that Studio Pierrot is not busting completely because even Naruto Series Anime might see an Abrupt end in that case...
