After a bit of silence on the topic Yoshida reconfirm in his recent live letter that the Beauty Salon will be making it to 2.1 as was suggested during the beta sessions.
While its too late to expect Square to be taking requests for the 2.1 release what are you crossing your fingers to see?
I'd be happy to just have access to a good portion other races' hairstyles. Sounds easy enough to add and would greatly expand options. Maybe for lore reasons limit players to their standard race hairstyles during creation, but able to get other race hairstyles from the salon.
Another addition I like to see in the distant future is being able to have multiple face paint layers. But that might be something for when the average PC is better and the PS4 has mostly phased out the PS3.
