That would make sense, I don't really follow the series as a whole, but lately I've taken more interest in it, and looked up some things.
Yes four million is a great #, and if it MGS:4 out sells MGS:3 then good for them, I just cant see it happening, at least not untill the accumulated sales from the next few years will be added together.
But Once again I feel the need to say, I created this thread to discuss why people think that this will be the defining moment for the PS3, but the same thing has been said for so many things I just don't understand why peole think that this game will make the PS3 sell more then the other consoles for a long period of time.
