GameStop has blamed a lack of blockbuster games and a misguided marketing campaign on what it says are 'disappointing' Wii U sales.
Speaking during an earnings call today, GameStop execs called Wii U's sales "disappointing", despite the sales figures that "exceeded our expectations" in its launch month of November 2012.
The retailer blamed Nintendo's marketing, saying that it has "not broken through the way that it needs to", noting a continuing lack of consumer understanding over the system's features, particularly regarding the GamePad. "We still have an education process we need to go through," it said, via Gamespot.
GameStop also blamed the lack of major titles for the system since Super Mario Bros. U, which launched alongside the system. "We're seeing the ramifications of that today," it said, adding that sales will "take off" when such titles eventually arrive.
Nintendo senior managing director and Mario creator Shigeru Miyamoto has admitted that the Wii U software library isn't yet as strong as he'd have liked, but says the platform holder is investing significantly in game development.
Nintendo has confirmed that a new 3D Mario action game and a new Mario Kart title are in development for Wii U, both of which will appear in playable from at E3 in June.
A new Smash Bros. game is also in development for Wii U and 3DS, but will only show up at E3 in 'image form'.
