So... we started getting information about MoP before Cataclysm's last boss was in the game. Now they're dropping hints about the expansion after MoP before MoP has even been released.
WoW Expansion 5 already confirmed by Blizzard
The Burning Crusade
Wrath of Lich King
Mists of Pandaria
What will be the next expansions?
So where to next?
I’m sure we can all be certain that a trip to Argus — to take the fight to Sargeras — will be WoW's last hoorah. That won't be en-route for expansion five, but could we finally dip into the emerald dream? I know its the go-to for all expansion rumors but will it be our next installment, or will the writing staff move into an area of lore once again untested and new?

I think we can probably expect the Emerald Dream and Nightmare next, followed by an expansion centered around Argus. Perhaps follow that up by a final expansion of dealing with the old gods, Azshara and tying everything in to a nice happy ending for the two factions. Then perhaps leave the servers open as primarily just a PvP game Horde vs Alliance...
What do you think will be the future expansions? Make speculations here and lets discuss it. :D
