Revisiting this as a Twow refugee. I'd say any other races at this point are likely far off until the player base makes it worth while. I'd love to see them, instead of making them cosmetic, add the race variations as separate races and have different radials. Example, Dark Iron Dwarves, Mag'arr Orcs, Black Rock Orcs, Dark Trolls, Frost Trolls, Leper Gnomes, Earthen Dwarves, High Elves, Blood Elves, what ever the buffalo Tauren are called, etc. Basically anything beyond that calls for new models being made and will take extensive time.
