Gamasutra is reporting that Nintendo has announced that in it's first 8 days on the market, the company has sold in excess of 600,000 Wii and over 450,000 copies of The Legend of Zelda: The Twilight Princess while racking up over 190 million dollars in total sales related to the console. In addition, Nintendo has stated that they fully expect to meet their goal of shipping an additional 150,000 - 200,000 consoles to the North American market weekly through the end of the year.
Those numbers aren't shabby by any length of the imagination, especially when you consider the console doesn't go on sale in Japan until December 2nd. I'd expect to see similar numbers coming out of Japan in the Wii's first 8 days there, and I expect to continue to see very strong sales here in North America. In other words, when you consider the fact that Nintendo is selling the Wii at a profit, someone is going to be getting one hell of a year end bonus.
From my perspective, the big question for Nintendo now is no longer if people are willing to try something new, but whether or not they can keep this momentum going and keep the public interested.
