So, I did a search and found no such previous topic. I noticed this on the flavor text of one of the BoA Weapons.
Zin'Rokh 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.So, chances are(this in addition to the fact that AQ is returning) ZG will definitely be back, which is awesome!perhaps the Soulflayer is not far behind
