I'm sure they're will be more races added with expacs. This is just the vanilla version of the game. They are making more content instead of a ton of races at the start. I can pretty much guarantee you they will for sure add new races..why wouldn't they? It's a planet that has recently been discovered and there are seems to be plenty of races making their way to the planet to colonize it. I'll take the content they have over extra races right now.
