I think that they haven't put in any short styles because of the lack of ears on the sides of miqo'tes' heads. It would (probably) look strange having a humanoid without ears in the normal place. If you think about it, pretty much all hairstyles we have now cover the area of the head where, if you were a human, the ears would be.
Back to the original post (and as I have said in a previous thread on the same topic) the hairstyle is different, but from the angle they gave us it looks pretty similar to the ones we already have. Having said that, you'd have to wait until it's released in game or they release a frontal picture to say for sure.
