I think the developers tried to meet the players in the middle by offering the bunny outfits on the Gold Saucer, and even working on developing them for men. So you have a way to...sort of get your Viera "fix" that way. I think that is as far as they will go, unfortunately for all the Viera-lovers.

Maybe we will see them in that new alliance?

Personally, I'd love a wolf/dog /fox type race
