They've sold enough of the backstock to need to make more of them again.
Mostly in part to the $99 price drop, along with recent bundle deals, the GameCube has been selling like a storm in recent weeks, not just here in North America, but across the world as well. Before that, however, GameCubes were being backed up in warehouses, and because of that production of the system was stopped in January of this year.
That's not the case anymore, though. For virtually the first time this year, Nintendo is restarting their GC production lines in Japan to restock emptying warehouses across the world, especially those here in the United States, where GameCube marketshare has skyrocketed to 37%.
George Harrison, Nintendo's VP of Marketing in America, said that the company hopes to sell two million more systems for the all-important holiday season. Additionally, cuts and bundle deals for Europe should mean increased sales for Nintendo of Europe's marketing efforts.
