More than likely, there will be a 2nd city. Maybe not called Dalaran but possibly in the same place it USED to be. Maybe New Dalaran?
EDIT: This is complete speculation (and I haven't gone through all the posts so excuse the repost if it's been said) but if Rhonin does die for some reason, then maybe they will call the new city Rhonin instead of New Dalaran. Just a thought....
Imagine that the flying city of Dalaran became full-Alliance.
Now imagine that in the dark places of the Undercity the Forsaken have been building a necropolis.
Now imagine Dalaran and the Necropolis going at war with each other in an epic air fight
Don't get your hopes up, Blizzard won't remove Dalaran from Northend, if they decide to bring Dalaran back there will two, one in Northend for both factions, and one in Hillsbrad for the Alliance.
this as the background sound. :P Then I could show them how I earned the title "Top Orc".
I don't really know how the quote relates to Dalaran at all but...
It would be great for the Alliance to have the old Dalaran location back, especially after the destruction of Southshore.
Rhonin is considered to be the leader of the Kirin Tor and I guess the "chairman" of the council, where we have Aethas, Modera as actual members of the six.
I don't know the fate of Ansirem and if he's still hostile to horde players after the changes back at the crater. Drenden I have no idea about anymore and if we should count Krasus/Korielstrasz as a member anymore idk. He hangs around Wyrmrest and died in the novels. So yeah.
I havent read the book and prolly wont but why would jaina kick out the sunreavers from dalaran thus kicking out the horde
Im not sure what information they got out of that horde spy in theramore but if i was aethas sunreaver i would just plead the fifth and say "dont blame me i didnt do it" and just deny everything sure she could have her suspicions but she wont the balls to throw them out of the kirin tor
Tbh i cant see them relocating dalaran any time soon if they was gonna they wouldve done it now in beta the time they bother to do anything with dalaran garrosh will be dead and her BFF will be back in charge of the horde and everything will be rosy again
