Is the new models coming back to Mists of Pandaria?

Since the 5.4.8 update of Mists of Pandaria the characters have got their older looks back with blurry faces and such and I was just wondering if the newer textures will come back to Mists of Pandaria but in 5.4.8 version? What will it take to get them back or is it undoable?

here are WoD models for a 5.4.8 client: http://forum.warmane.com/showthread....ated-for-5-4-8
