So as you guys may or may not know, the Zul'Gurub raid portal has been removed... and there are no mobs in the Zul'Gurub zone. Also in the archeology text on Zin'Rokh Destroyer of worlds it mentions something on the return of Hakkar:
"According to your research, this great weapon was one of the many treasures of Hakkar the Soulflayer in Zul'Gurub. Hakkar was defeated years ago and this sword passed through the hands of many powerful warriors and paladins before apparently becoming sundered. It is remarkable that you have been able to reforge it, but also a little troubling that if the Destroyer of Worlds has returned, perhaps the Soulflayer is not far behind."
Do you guys think this means that Zul'Gurub will return as a cataclysm raid?
