Pandaren would be my guess.
Shaman since Vanilla. All the way !
Well, the Pandaria candidates are of course Pandaren, Mogu and Mantid. I would expect to see at least the first two, the pandaren for obvious reasons, and the mogu because they had an ancient huge empire in pandaria. The Mantids though still fit in well, but it depends on how much time blizzard will put in.
To be honest though, I doubt it takes that much time to create a few digsites around the place, some gray items, write up some lore and then throw in a few rares.
