Laoldar, I tend to disagree with that idea, I think this game will be huge in America anyways, as if you look at historical data, the Pokemon games have always sold more games in America than in Japan. America has a little under 12 million DSs sold already, Japan has a little over 16 million, but considering that historically this game has always sold better in America, the game will be huge anyways despite the apparent loss of sales due to less DSs sold in America.
Also, we are looking at lifetime sales, so why say that the game won't be huge for several years then revise downward the lifetime sales? This game might not get the 1 million sales explosive start that some may be expecting, but still expect this game to have a huge long tail that will eventually give this game a large amount of copies sold. I think Pokemon Diamond/Pearl can sell 17 million copies, it just might take awhile to do so.
