Just that it's still coming along.
Also for now the new chapter is still considered just a one shot, the manga hasn't been picked back up again. Though I'd imagine if the show performs well then they'll most likely get Kubo to continue making the series.
I remember seeing some time back with Burn the Witch how Kubo was supposedly planning on doing the manga in a seasonal format, where he'll work on it for awhile and then take a break from it. If Bleach were to return, the way he could go about that is by shifting between the two series. Work on BtW for a few months, then switch to Bleach, maybe take a month or so off in between then go back to the other, and so on.
