Wii U game sales behind both Wii and GameCube sales

December’s NPD results are finally available and there’s been something of a shocking revolution for Wii U software sales. No Wii U exclusive title was found anywhere in the top ten sellers for the US. This leads many analysts to believe that the Wii U’s early sales could mean an uphill struggle is on the way for Nintendo. According to Analyst Doug Creutz of Cowen & Company, sales were below the last two consoles.

“Totals for the November-December period were -43% lower than software sales for the Wii and -50% lower than those for the GameCube.”

Currently the only US Wii U software sales number to be released by Nintendo has been sales of New Super Mario Bros. U, which clocked in at 580,000 units for the months of November and December. With sales going this poorly, Nintendo is going to need to step up courting third-party developers to make sure they’re targeting the system instead of the constant news reports of games that aren’t coming to the Wii U.
