I don't know if this was pointed out by anyone before, so I'll just go ahead and mention it.
I looked at the map of Tyria which is blank but has all the zones unfogged including Labyrinthine Cliffs which we can no longer access.
When I looked at Orr however I found something "strange" there appears to be another zone there south from Arah on the southmost part of Orr:
Any idea what could that be? Next LW area perhaps? I mean it would make sanse for Joko to go to Orr next as there are plenty of masterless undead there now.
