I have the annual pass and the game isnt even downloaded yet, i did beta till level 5.
Diablo isnt for me, especially as i see my wife playing a "halo kitty" and "ponies friendship is magic" bonus stage next to me :P
And no RMAH is not even wonderfull, it is gambling through a video game. Gambling is addictive more than the game itself.
I' ll keep clear from it, and any other product blizzard brings to that direction for ever!
