The poll thread also has this line,

Ours being a Japanese game, the result seems to tell us that players are prioritizing cuteness, something which I noted with great interest.
Which should always be something to be wary about, especially when it comes to an apparently beloved race like the Viera (and it doesn't help that there is a "cute child-like" concept of them, which even has Viera fans arguing/disagreeing amongst each other).
If Viera were to be playable at some point, then I'm hoping the next playable race will at least be something like the Lupin. Throw in something different and original into the basket SE, come on.
