I think they are a bit behind the curve right now. Sony have had some small F2P games already and successful from what I understand. MS are coming late to the F2P party. Add to that that you need gold subscription to play and you automatically exclude a whole bunch of potential customers and limit the game to approx 20M gamers (correct me if Im wrong). And I dont see F2P games as ones that will make gamers get gold subscriptions - since I would assume getting a $50/$60 subscription entirely defeats the purpose of playing F2P games.
