Nintendo of America has projected that the Nintendo DS will be the best-selling piece of gaming hardware of the year in the United States, with internal figures indicating sales of more than 6 million units through to November 30, 2007.

“There’s no letup in sight,” said George Harrison, senior vice president of marketing and corporate communications at NOA. “Nintendo DS appeals strongly to both core and casual gamers, and its momentum is set to propel us into 2008.”

The Thanksgiving sales week most recently passed, and Nintendo DS managed to break the all-time sales record for that week with more than 650,000 units sold – topping the Game Boy Advance’s previous record of 600,000 units in 2005.

Four Nintendo DS games have sold more than 2 million copies to date in the US, Nintendo also said, including New Super Mario Bros., Mario Kart DS, Pokémon Diamond, and Super Mario 64 DS. Games to have broken the 1 million mark include Brain Age, Pokémon Pearl, Animal Crossing: Wild World, Big Brain Academy, and four versions of Nintendogs.
