Not really anything extravagant but this image is from the 8.3 PTR in regards to the Allied Race character creation screen:
The open spaces at the bottom scream to me at least 1 more Allied race per faction is coming. I also could not imagine they would not come in Shadowlands as Allied Races were marketed as a Battle for Azeroth feature and Blizzard has already stated the initial/beginning story of Shadowlands doesn't really allow for new Allied Races.
Or I could just be over thinking things and it's just a PTR mishap. /shrug
Now that Vulpera are being added given the almost 2 years debate over them even being wanted/unwanted by the WoW community I feel as all bets are off in terms of what races would "fit" to be added. That being said I can still see either:
-- Jinyu for the Alliance, Hozen for the Horde
-- Ankoan for the Alliance, Kelfin for the Horde
...or a combination nobody has thought of yet.
Thoughts? 2 more races incoming? Or just a coincidence?
