Nintendo 3DS sold more consoles in Japan during December than any other machine on record.
Enterbrain (via Andriasang, naturally) has been tracking console sales since 1997. Nintendo sold 1,492,931 3DS systems between 28th November and 25th December, beating any other console in Enterbrain's books.
Last week it was revealed that 3DS hardware and software were 2011's top sellers in Japan.
Nintendo's quarterly sales report is due before the end of the month, so we'll soon see whether this record-breaking sales period is enough to put the company back on track for a profit.
