Shamelessly reposting for those that don't read the Japanese thread:
"As for the Bleach ending thing, people are really freaking out over nothing. You guys know that Kubo considered everything from after SS to the start of the Lost Agent stuff to be one arc right? That was a good five years of manga, and he has already said before that this next arc will be longer.
These past interviews have shown there is quite a lot of content to cover, so he could make the whole ten year claim. That's assuming this is actually the final arc, who knows how he will feel about it in five+ years time.
Remember Toriyama planned to end DBZ several times, but by the time he'd get to the end of the "final" saga he'd extend it further. "
