Will more races and classes be available when the game is released?

Edit: I bought this game and I love it! It is an instant classic

From what I've read, sorcerer class will be available when the game officially launches. No more races coming though.

Just buy it. The game is a superb presentation of the 5E SRD rules and feels much like my old AD&D table top days.

don't know myself but would also like to see more races & classes represented. That being said, BUY IT. As mentioned by others, it's still a great 5E engine and so far has been worth the $$ with promise for more campaigns (either community or official).
