Looks like we have our conformation that this show will be going on for a while. There's a PV one the official site which shows content from what looks like the next arc after the events we are watching now. Will point out that it does feature quite a few spoilers from the next arc, though at the same time it's great to watch so we can see what's going to come next.
It's the second video link on this page:
