DFC Intelligence has predicted that the Wii U will shift only 25 million units by the end of its lifetime – placing Nintendo’s latest console slightly above the Nintendo GameCube, which sold roughly 22 million units. On the other hand, the Wii – which was released in 2006 – has surpassed 100 million lifetime sales, making it Nintendo’s best-selling home console.
Wii U “is expected to be mainly a system for Nintendo first-party software,” DFC Intelligence wrote in a market research report provided to IGN.
“[Its] sales [are] anticipated to be only about a quarter of the Wii.”
