I'd me more excited for a new class than a new race. But, that's because I didn't enjoy Monks or Demon Hunters. I really love my Death Knight, though. I'd rather see the existing races get some love than have them add new ones. Give everybody their own cities, and toss in reasons for people to actually visit them from time to time. Let the poor Gnomes FINALLY have Gnomer back. Cata was such a tease for them.
