I’ll be blunt and link it to the American topic which also includes some pictures. Take it with a grain of salt for now:
Don’t get too excited. The new raceIDs in this picture are 15, 16, 17, and 18. All of these numbers are already claimed by existing races that are almost certainly not going to be made into playable allied races. Respectively, these races are;
Skeletons.
Vrykul.
Tuskarr.
Forest trolls.
I wouldn’t be suprised if they added a last pair of ARs in the SL pre-event to fill the last panels in the chara creation screen.
With the transition to Shadowlands they have more freedom in possible races (less about recruiting for a faction conflict).
Also a new AR for the prepatch would give them a lot of useful data for the new leveling changes (and more players get to see the new starting zone).
But maybe it’s more a wish thinking that Mechagnomes aren’t the final AR for Alliance 
We may not be the final AR for Alliance, but we’re the pinnacle of races.
You’re an amputee abomination 
(they’re pretty neat if you into that kink)
If there are four new ones we could be getting a race from each covenant. Though it’s hard to say which ones would join which side or if they would be the first neutral ones.
Though they might just give Killian to the Alliance and Venthir to the Horde purely because of Blue and Red.
Then it would be done the same as the Pandarian.
I don’t think Covenants would be right though.
I think it’ll be “sub-races” of what we already have.
The only allied race I care about is the Jinyu. Even though they’d be alliance.
Jinyu and Hozen should absolutely become allied races. They have been in the Alliance and Horde for so long now. Also Ogres for the Horde! I would race change into an ogre mage instantly.
Pls, be OGRES!
Ogres would very much make sense. They could use the Kul Tiran model but modified of course to achieve that. Only problem is how would they fit into the current story in SL.
I dont see much talk about Ogres. Then again Machagnomes sort of came out of nowhere so you never know.
“Me smash skulls before, now me smash ghost skulls.”
Here is the lore.
Main concern probably is still the female ogre design. But maybe they finally able to do it.
If you want to play female ogres, then the Alliance and the KTs are there waiting for you. 
We already have waaaay too many races, so this better not be true 
Nah, KT female is nowhere near close to the “ogres”
Why is it a problem to able to choose from more races?
Lets be honest ,this is best potential allied race
All I want is Man’ari.
pygmy, kobold, leper gnome, gnoll,
Players have been waiting for them for long time now.
Won’t someone please rid me of these meddlesome allied races.
One of them is going to be Sethrak. I’ll bet on it.
Panda lol
Because narrow mindedness my friend.
Bring us all the races!
