He doesn't have a crystal ball.

They're going to roll out the game and see how it goes. Can you predict with accuracy how it will turn out, oh wise one? Of course not. Neither can Blizzard. They have to build it and see how wow po it turns out. Then they can determine if and when to open up flying.

Trying to find out now is not going to end well, because there is no answer to give. They aren't hiding anything; Blizzard simply doesn't have the data to make a decision at this moment.
