The poll never asked "Do you want Viera?" The poll asked "What type of race or clan would you most like to see added in the future? Mammalian demi-beastmen (ex. a rabbit-eared race such as the Viera from FFXII, etc.)" It is not Square Enix's fault that people have no reading comprehension, nor cannot use Google well enough to dredge up the correct information and realize they are spreading misinformation. Examples are not a "do you want this?" They are a comparison for something they already have in mind.
Here, I'll even link you the thread. http://forum.square-enix.com/ffxiv/threads/46936
EDIT:
Looking over the poll again, I also just realized this myself. The final question doesn't ask player characters, only simply asking what types of races or clans would players like to see added along with all the values in which each region felt upon the choices. We will be seeing Viera in Return to Ivalice. We have the Lupin for mammalian beastmen, the kojin for reptilian beastmen, the au ra for reptilian demi-beastmen and Hilda? (jeeze I already forgot her name) from the Heavensward MSQ for more mixed races.
