I haven't seen anything (other than the art)* that would turn me off of the game, so I'm in. In a lot of ways, from what I've seen it's closer to what I want from D&D than any version that's come before, except possibly the game that's implied but not actually explained in the old Basic/Expert game.
*I don't think it's possible the art could actually cause me to not play the game. It hasn't stopped me yet, and there's been a lot of really terrible D&D art.
