I did notice at the end of that poll that they didn't specifically say whether or not we'd be able to "play" a new race, just what we'd like to see added.

I also think he was right when he said the results were probably skewed because he used Viera as an example of the Mammalian demi-beastmen (Bad choice as an example really).

If they ever do add a new race, and if it turns out to be unplayable like the Padjal, I'd rather they went with the second most popular vote on that Poll (the mixed races).
They've had mixed race experience in their previous MMO, FFXI, anyways with Lilisette.
