He forgot to add where you shouldn't get your hopes up because no one knows when the game is coming out. He also forget to tell you that you shouldn't get attached to the game until well after it's out and Battle.net is fully acclimated to the game, so you probably won't be able to play it. Also, there is a small probability of you being accused of gold selling for not good reason and you will lose access to your account for a short amount of time (or maybe forever, who knows, no one can know).
Then the other guys correction would go something like this. It'll be out soon, don't worry! And battle.net is the sweetest thing on the interwebs, so don't worry! And don't worry (!) about gold selling, as long as we get our cut, your account is safe.
