There is nothing official by season 2 yet. Have you got some official link regarding this? as far as i know they are waiting to see how the rating goes before they decide go for season 2.
Agreed Fatalmephisto, I personally know five people that left the game within the first week and after the first episode are now the hardest core player you will ever meet haha they are hooked and the show will do that to people, my younger brothers also got hooked after the show even though they weren't playing before then. The show will draw more people in and the game will just make it MORE fun, I don't think the game will draw people to the show though because the show is why most people play anyways.
I THOUGHT DEXTERS WIFE WAS DEAD!!!!!!!!!!!!!!!!! OMG I am so happy now!
