Hard to say. Anime's have been canceled before due to dropping popularity at godawful points, quite a few due to overlong filler arcs too. However in this case it's like the entire Bleach series is being aborted, with both anime and manga getting the kill notice. It's kinda hilarious how hard Bleach has tanked lately ratings wise, which for something that used to hold a solid place in the top 3 is pretty much a first to my knowledge.
Mind there was a minor bit of conflicting information on this. Someone looking at a schedule in Osaka or something found some kind of lineup for april that seemed to refute this, but at this point it's been confirmed on both ANN and by the director of the anime himself that it's getting canned. So most seem to think that the reason the schedule still says its ongoing in that one station is because they hadn't updated yet or something.
I'd keep your ears open for any additional news if this pans through, but I certainly wouldn't get your hopes up.
