Jordan Lund analyzes the sales numbers coming from Black Friday in the US.
Excerpt: "In terms of raw unit sales, Nintendo takes the top spot for the holiday by pressing 4 unique and distinct product lines, selling a grand total of 1,225,000 pieces of hardware. The bad news for Mario is that, in their heyday, both the Wii and Nintendo DS would have exceeded that total number each on their own. November 2009 for example saw the Wii sell 1.25 million and the NDS move 1.7 million. Dropping to just 300,000 and 275,000 respectively is a huge downward slide. Wii U sales might have been limited to stock on hand, but it’s also 200,000 units less than the Wii sell-out in 2006. Shy of the higher price, it seems like Nintendo simply made fewer Wii U machines to avoid being left with stock on hand."
