Nintendo of America has issued a series of facts and figures for its Holiday period performance in the U.S., following publication of the latest NPD figures that cover 25th November to 29th December. There were some solid results and, perhaps most importantly, decent figures for Wii U sales in December after the launch week rush.

In terms of Wii U, total console sales in the U.S as of 29th December were nearly 890,000 units, while special mention was made of New Super Mario Bros. U with over 580,000 sales, an attach rate of over 65%. Those aren't bad figures after 41 days on the market, though don't match up to Wii which sold around 600,000 units in just eight days when it launched. Scott Moffitt, Nintendo of America’s executive vice president of Sales & Marketing, has focused on an area where Wii U has out-performed Wii, by virtue of its higher retail price; Wii U hardware sales have generated over $300 million in revenue during this period, while at the equivalent point Wii hardware had generated just over $270 million.

While the Wii launch established new benchmarks in the United States, Wii U has surpassed its predecessor in perhaps the most important category: revenue generation. The demand for the Deluxe SKU, which was essentially sold out at retail this holiday, and the strong attach rate of New Super Mario Bros. U, shows that we have the value and the games to drive momentum in 2013. We look forward to offering great new experiences and bringing smiles to millions of new faces throughout the year.

There was particularly good news for 3DS, which after a rough Black Friday of being outsold by DS bounced back with a very impressive 1.25 million sales in December, taking the US lifetime total past 7.7 million units. That was quite a haul over the festive period, while New Super Mario Bros. 2 also performed well, becoming the fourth 3DS game to pass one million sales in the country with the lifetime number at a healthy 1.45 million units.

Nintendo's older systems, no doubt boosted by budget prices, showed life with Wii selling nearly 475,000 units and DS shifting nearly 470,000 units in this NPD report's period; that takes Wii to 40.8 million sales in its U.S. lifetime, and DS past a whopping 53 million. There was also a mention for Just Dance 3 on Wii, as it became the 10th title on the system to pass 5 million sales in the country.

Lots of facts and figures there, with 3DS arguably being the star of the show, while the combined figures meant that this was the 11th consecutive year that Nintendo has sold over 8 million hardware units in the U.S. There's been a bit of spin applied by focusing on Wii U revenues — they're higher as the system has a meatier retail price — but nevertheless these seem like good results for the company.
