I'm just going to say this before I get into the actual story; this is a publicity stunt. They aren't actually going to end the Bleach anime. It IS going on hiatus it seems. It'll be back in a year or two as Bleach Shippuden or something to that effect when the manga has built up some headway.
But yeah, so the animated version of Bleach is going to be taking a little break from existing for a while, and the official word doesn't indicate a return. Which is probably for the better, lest it go on some filler run like some of its contemporaries. This break will align to the end of the current Fullbring Arc. Why they waited until now instead of doing it during the time skip is beyond me. That would have made so much more sense. It's even more shocking considering this break seems like it has been planned since before the arc started; If you watch the opening, they show the middle title cards of several past episodes, seemingly in tribute.
So for the fans of the animated version, get your fill before March 27th. It could be a couple years until we see Ichigo in all his animated glory again. And I'm totally okay with that. Because when it comes back, it'll hopefully have 15 whole minutes of new content each week.
