Wii U has not enough customer base
"...Following this idea that Take-Two's content goes where the consumer goes, Zelnick spoke about the company's relationship, or lack thereof, with Nintendo and the Wii U console. Take-Two believes that Wii U just doesn't have the consumer base to warrant its attention right now. "Our strategy is to meet consumers where they are," Zelnick elaborated. "If they're buying hardware, we'll be there with software. That said, we make these really big, AAA titles that work on some platforms, but not others."
