Revamp Vanilla models? Plz?

I'm not sure if something similar appeared already, I didn't saw it on forum or maybe I missed it somehow. But anyway I have a question which is about incoming Cataclysm.

There will be new races, and Azertoth also will be changed. Environment will look more decent in graphical way because of new graphic factors (let's call it this way), but what with old vanilla races? I like them very much but the fact is, their models are old and don't look as neat as new ones. I can even tell that there are bugs in animations. Is blizzard planing to do something with it, there will be new face models available, and/or hairstyles?
