Gotham City Impostors Free to Play

I just saw a starter pack of the game in the Steam page where it says Free to Play

Presumably the game will be Free to Play but for those who bought the game and the DLC, what will happen?

Besides that, the game uses GFWL*, did you take off? (would be appropriate)

Sorry for my English xD

*GFWL = Games for Windows Live
