I'm pretty confident that for whatever reason (yoshi thinks male rabbits are weird) Viera will be gender locked. Let's just accept that that is how the start of shb is gonna be. But I'm also confident that, if people keep asking, male viera and female hrothgar will be added. Yoshi said they added female viera just because it kept being asked for, so if he doesn't want to keep hearing "when are you going to add viera?" he'll give y'all the man buns.
