The first patch will be released the 17th of August. That patch contains a lot of bug fixes. I understand how you feel about the early release, but you could look from it the other way around: you can already play the game and it only gets better and bigger with the patches to be released. If the release date was posponed, a lot of bugs would still have been in the game (because you hadn't told us) and you had to play the old version for much longer.
