Street Fighter has been released on many different Nintendo systems over the years, unfortunately that doesn't seem the case with Nintendo's home console. Series producer, Yoshinori Ono, said on Twitter that Capcom has no plans to release Street Fighter IV, or any other game of the fighting game series, on Wii U.
When asked about the possibility of releasing a Street Fighter game on Wii U, Yoshinori replied "We apologize that we don't have plan about it at this moment." However, despite what Yoshinori said, he didn't rule out any future possibilities.
For now, it seems like that fans of the genre will have to stick with games such as Injustice: Gods Among Us and Tekken Tag Tournament 2: Wii U Edition.
