I honestly think it was a very stupid move of them to pull the plug right before the final arc, this new arc is going to go for at least a year, maybe two, the Arrancar arc dragged on for 4 years and Kubo said he wanted to continue Bleach for another 10 years, we can probably look forward to a long arc, and that could have given the Animation company plenty of material to animate, not to mention the views they are losing by ending Bleach at what is IMO one of the worst arcs Kubo has written.
