Since it seems like almost every race is getting a range of eye colors as well as a range of skin options from Light to Dark it's only practical for an opening of diversity to occur within the Allied Races, and here specifically - Void Elves.
Unfortunately AR fans will have to wait till the original races are all done up first. Which I assume the additional options for original races will all be done by Shadowlands hitting live servers. Then the focus will move to Allied Races.
