So I believe there are two distinct possibilities that could happen.

the hopeful one:
People have been asking for more customization options for a long time and this expansion will be big for that.
I noticed the viera has a new face tattoo so i'm thinking we are going to see some new expansion option in the CC.
With that they are also going to drop 2 more races and it will be the big feature of this expansion. CUSTOMIZATION.

the sad one:
Viera female/ Hrothgar males.
