well we all know that Cho'gall's connection to AQ. Now in 4.1 PTR Blizzard has added new quests to silithus.
In addition 4.1 also comes with a new icon for a very old axe
So do you guys think that Blizzard is going to revamp AQ in a future patch? Personally i think they will just because of the tie in with Cho'gall. Or maybe C'thun is homeboys with N'zath (sp?).
