Bah. They spend a bajillion hours on pretty graphics and only 20 minutes on something as important as hairstyles? Get your priorities straight, kids.
I think you answered the question - while I definitely would have loved, you know, hair that moves and more than 2-3 styles that aren't all variations on tomboyish buzzcuts, if I had to pick between what we got and getting amazing hair but losing a chunk of game content as a result, I think I'd suffer the hair issue for now.
That being said, still think it shouldn't have been a case of "one or the other" and while I highly doubt they'd patch in new hair, I'd love to be wrong. Especially given some of the cool concepts that were made of Qunari females with some savage looking hair styles.
