Also, you seem to think that games only make profit when they sell a gajillion copies on the first hour. Even if Chinatown Wars doesn't become a monster hit its still profit for Rockstar and that's what all game companies really want.
You have no idea when the game becomes profitable. There is a break-even point based on how much it cost to develop, publish, and market. We'll never know if Chinatown Wars becomes profitable -- we can only assume that it will if sales numbers get pretty high.
Adolph, there is no way U.S. sales will reach a million this year unless the trend reverses with a major spike upwards. I think it's totally possible, but it won't happen naturally. Rockstar and/or Nintendo would have to do some new marketing to counteract the natural decay of sales over time. They also need to worry about keeping it on store shelves so people will actually see it when they go shopping, as retailers (especially Gamestop) don't display games forever, and the most visible spaces always go to the new/hottest titles.
