The more, the merrier no? laugh
Personaly i would hope for any of following: Deep Gnome, Duergar, Tabaxi, Arakokra, Genasi, Lizardfolk or Aasimar ...

But quite honestly, it doesnt really matter how many other races we get as much as how well they will be implemented. :-/
I meam if i get Deepgnome ... but Duergars from Grymforge will not try to enslave me on sight, it would be quite disappointing. frown
So ... in such case it would maybe be better to not implement them at all. :-/

I still dont understand why cant we change Race for our hirelings. frown
Lets us play Githyanki as racist as they trully are! frown
