I mean it is possible that Nintendo makes sure to withhold stock of systems, like the Wii, to just beat the previous Nintendo console, and then with the next console they make sure to make a little more than that to say, "Oh, we beat the Wii everywhere!" Personally, I think there may be a little of that at play, however, those sales still aren't guaranteed. If the demand isn't there it can blow up in your face when, even with the plentiful stock, people aren't buying them and there are shelves piled with them. That's a bad image in consumers' eyes. It can also blow up in your face, even if the launch part works, and demand falls off a cliff. People will then say, "So what if you beat your own launch records, nobody but your fans really wanted it."
