If this really is true, with the implication of a burning legion invasion, i speculate an Outland revamp in the works and who knows - maybe Ogres next xpac? It ((In the Best Buy Q&A.
Were Ogres ever thought of as a playable race, at one time? (Greg marry me /kiss) Irth
Ghostcrawler: Yep. We considered them for Cataclysm instead of goblins. Figuring out the females and the two-headed mages would be (fun!) challenges. Maybe someday.))
Also, the Mogu remind me of ogres (just with hooves) so it is possible they might be working on ogres. It also makes sense to have new races for the next xpac.
From a story perspective, we might even be saving both Turalyon and Alleria after they 'disappeared' following that old 'lost battle' in outland.
Also: Return of Kil'Jaeden in his true form. (lol)
There was also some mention of warlock content coming in the future. Wonder if it has anything to do with Xoroth.
Once again, this is just my speculation. I could be wrong.
