Dragonborn and or half orcs would be a nice addition to see come in along side the paladin / barbarian classes at the same time for a larger character build. Dragonborn is probably the most requested race outside Aasimar hopefully it would come in with the barbarian class as they would want to add a larger character build model to go with it a more I am burly model and that would be a good way to introduce it which would also make added half orc an easy added in option to follow suit on it and we would get first look at what Larion is going to do with less humanoid appearance races I am hoping we see something similar to alot of the models from the phb and what not and hopefully far away from divinity lizard men in the look. I feel like next race we will see will probably be gnomes however with a durgar add since they already have models.
It would make sense to do the dragonborn with the barbarian however as it would be a really good tie in with a more ripped jacked up male model and the option to choose some variation in character size at character selection. + They already have some barbarian starter gear appearances in the game files so hopefully.
