U will have to wait.
The release of Watch Dogs for Wii U has been delayed. The Wii U version of the game has been pushed to, simply, "a later date".
An Ubisoft spokesman had the following to say about the delay: "We made the difficult decision to further delay the release of Watch Dogs on Wii U to focus the team's resources where they could have the broadest possible benefit for both our customers and Ubisoft".
Watch Dogs was originally set to be released on Wii U between April and June 2014 along with other platforms.
