OK, perhaps a bit early but a little specualtion based on events from cataclysm.
Vol'jins considering leaving the Horde.
Sylvanas is setting the stage for getting kicked out.
The Grimtotem are working with the Alliance.
The Dwarves probably won't be too pleased if rumours are true.
Could the next Xpac see the end of the current Horde and Alliance as we know it and a reformation of both around all races?
