Also, I don't think it's that difficult to incorporate the "possibility" of having rumble in a game. There is, after all, an option to turn it off, yes? If Sony knows it will exist, it wouldn't be hard to say, "Go ahead and code for it, we'll have it eventually." And that would please Kojima, no less.
