Hahaha! Suck it, Studio Perriot!
My irrational hatred of the anime aside, it's likely just a hiatus. People didn't like the Fullbringer Arc, to be sure, but Bleach's ratings aren't cancle-bad (yet). The problem is that they're close to being done with the arc and there's nothing left for them to animate, and they just came off of a lengthy filler arc. Even if Kubo hadn't taken 5 weeks off they still would have needed to take a break.
Bleach is still too profitable to drop. If word get's out that Studio Perriot dropped the license, then you should start to worry. Or celebrate, because that means a competent studio might get a chance to do right by Bleach.
EDIT
Turns out it's just moving time slots. Fowey.
