Meta-wise, Viera are much more requested and tie in better with Ivalice. That said, Yoshi DID consider adding Viera in HW only to veto them for being too "human-looking" ...then cannibalizing the Viera designs to make the Au Ra more hyru-like... so I wouldn't hold my breath for more bestial races, if they still have that mindset it's unlikely we'll see any races that are more bestial than "animal ears+tail" combo. It was always a bit of a stretch when Yugiri got introduced and had to cover herself, then HW stated how Au Ra were facing discrimination for looking like dragons (to the point of being sot on sight) yet you could make a lvl1 Au Ra character and not be treated differently by the MSQ.
