Official NPD numbers for December aren't revealed until January 14, but that hasn't stopped Nintendo CEO Satoru Iwata from tooting the company's money-making horn.

According to Iwata, Nintendo managed to sell over 3 million Wii's last month in the US, beating last year's 2.15 million and toppling the previous home console record held by the PlayStation 2 at 2.7 million units during December 2002. The DS managed to move around 3 million units in December 2008 in the US.

No doubt this came about through the perfect storm of holiday shoppers, ample supply and a reduced price. It's likely that New Super Mario Bros. Wii had something to do with it too, which Nintendo says is approaching 4 million units sold.

Nintendo is also touting additional impressive sales records across the pond. The Wii's European sprint to 20 million sold units is the quickest reached by any console in the region, and the DS family's over 40 million units sold makes it the best-selling gaming system in the region ever.

Where oh where will they put all those piles of money?
