Seems like Bleach may be returning to Karakuri Town...about time actually, since the Ulquiorra fight was a disaster.
As for Neuro...I don't consider it a failure at all on Matsui or the series fault. Unlike many other Jump series, Matsui actually did what he wanted to do in four years: get in, tell his story, get successful, get an anime, finish his story, get out. Compare that to a ton of other mangaka who try (and fail) to write massive, year-spanning epics...and you could say that Neuro is the real winner. It'll be sad to see the series go but I think Matsui is better to move on to bigger (and stranger) things.
