They just need to put out a statement about Hrothgar and that adding a beast race makes adding hairstyles and hats/helmets for them a very hard process. But that they will fix the Viera hair/hats situation in the meantime while they figure something out for Hrothgar.
Now, by me saying this it's not that I'm opposed to Hrothgar getting fixed, but let's also be honest about the Hrothgar situation, their heads are animal heads. Fitting human hair on animals heads is a task and half whether in real life or in game.
People who asked for beast races know that this is a problem throughout many mmorpgs and here we are
When they said Viera/Hrothgar would need their own unique hairstyles, I can see why it would apply to Hrothgar, not really to Viera. Viera is just Miqo'te or Hyur with rabbit ears when we strip things down.
