Where did it say there would be additions to the Character creator? Sorry I didn't see that anywhere...
I haven't seen it mentioned either. If anything they'll add more hairstyles to the races that are lacking. Some of the races have 8 styles (and some with variations) while others, like the Lalas, only have about four styles at the moment. I don't really see them adding even more styles to the races that already have a full plate, but I could be wrong.
During the different phases of CB the models were occasionally updates with additional things you could customize so who knows what's in store for retail.
