I feel like the reason viera and hrothgar haven't gotten more hairstyles etc. is because they are working on the other genders and will release all with the next expansion, completing the current genders options and adding the missing genders. As well as updating customization options for the other races. I mean, come on, our character creation system is getting seriously dated even compared to MMOs of the SAME generation.
If this doesn't happen, then yeah, I'm probably done too.
