With the threat of the Scourge diminished, the Lich King dormant or under Bolvar's control, and most of the lesser foes in the Plaguelands defeated, will they someday focus their attention on the Forsaken and join the Alliance? Could we see another neutral faction picking a side, just like the Kirin Tor did?
I would welcome this move. The Alliance needs a foothold in northern Lordaeron, as it's pretty much under Horde control.
