Yes I know about the rule of concept art. But SE knows the rule about showing these things to players during fan festivals, Viera were shown live AT fanfest 2014. I was there, I still have PICTURES on my phone from it. They discussed the vote, they showed viera, they showed Au Ra. If you've reached a point where you are showing those images live, the precedent is set that you're going to implement them at least in some form as they'd been shown. In this case with males and females present. Yes Au Ra did females came out much different than the weird ring-girl succubus looking thing they presented. But they CAME OUT. They were pictured, they were changed and they made it.

Game companies try their damndest to avoid showing things unless they're for sure going to put it in, because it becomes VERY messy if they don't end up implementing it.

I hate to use blizzard as an example, but...seriously. They do not show development concepts to the general public for this specific reason. the general public doesn't typically get that stuff until the game is released or VERY late into development where it's for sure in, but maybe tweaked a bit, as a perk for buying the collector's edition. Artbook. Post-implementation. I used to work there, there is tons of stuff the general populace never sees, but you dont SHOW it for this exact issue's reason.
