I think people are getting their hopes up too much for drastically different subclans. For one, they already spelled out what the Viera ones are (Rava and Veena), and two, subclans having different models like Hyur is the same amount of work as two races, even if they take shortcuts and share all emotes/animations, it's still a lot of additional assets to make when we already know they're going out of their way with viera hairstyles having bangs on/off variants and had to do some kind of change regarding helmets for them.

There's wishful thinking sure, but people maybe need to adjust their expectations based on the likely reality of the situation.
