If activision does try this, then it will be the death of CoD because they will not be getting the sales as they did before. This is not World of Warcraft where people will pay for an MMO each month. It might work for the first 3-6 months, but after that, it will die and then the next CoD will not even be a blip on the rader screen I believe.
Again why pay for something when you can get it for free? Then again, we have all these idiots who pay for itunes, so maybe this Activision CEO is onto something. We already have millions of people paying for music wich they use to get for free. So what do we know? He is rich really rich, and what are we? Not close to him in the money scale that is for shure.
