Wrath of the Elements

Little progress has been made toward mending Azeroth's dire condition. Thrall has nonetheless continued forging ahead in search of answers. Most recently, he journeyed to his ancestors' lands in Nagrand on the shattered world of Outland. At the fabled Throne of the Elements, he has met with other wise shaman, including the venerable dwarf Gavan Grayfeather, hoping to glean even the smallest shred of insight that could help him save Azeroth from ruin.
Meanwhile, Twilight's Hammer cultists have been caught infiltrating Orgrimmar and Stormwind City, sparking panic and suspicion among the two great cities' inhabitants. Although the cult's earlier bid to wreak havoc on these capitals had failed, this new development has raised fears that the Twilight's Hammer is poised to launch another, far more devastating attack.
The events leading up to Cataclysm are underway and a great disturbance of the elements has erupted. Don’t miss out on the all-new quests featured during this one-time-only series of events.

It's not like WoW can last forever...unfortunately. If the factions all joined sides, how would a Warcraft IV work out?
I am also thinking that if they ever allow the joining of the two factions, it'd either be by adding a sort of neutral faction (where you'd shun your other faction or something) or it'd be during an expansion where the world of Azeroth finally join forces once more to bring an end to the Burning Legion.
