[Update: Sorry, but it looks like I got this one horribly wrong, folks -- the WSJ was in fact referring to November sales. Thanks, Jay!]
Big surprise: early reports from the NPD indicate that the Wii utterly owned December, "doubling" its sales from December 2007. As it shifted 1.35 million units a year ago, that means this December saw approximately 2.7 million Wiis sold. For those who care, PS3 December sales dipped 19% from 2007, while the Xbox 360 got an 8% year-on-year lift.
More precise data concerning the Wii won't be released until the middle of January, but this could mean the Wii breaks the all-time record for U.S. hardware sales in a single month. Currently, the PlayStation 2 holds that honor, with -- aha! -- 2.7 million sales in December 2002. It's going to be close, in other words.
