A dry but happy piece of business news to start your week off: Wedbush Morgan's all-seeing analyst Michael Pachter reckons Wii sales in the U.S. accelerated dramatically over the holidays, with Christmas figures "up more than 100%."According to Pachter, that translates into "around 3 million" Wiis sold during December. As we previously mentioned, the record for U.S. hardware sales in a single month is 2.7 million, a figure set by the PlayStation 2 in December 2002. When the latest NPD figures are released on January 15, it looks like we'll have a new record-holder. Nintendo obviously didn't get the "recession" memo.
