Update: Ubisoft confirmed a November 18 release date for Watch Dogs on Wii U. That's for North America, with Europe locked in for November 21. Ubisoft's press release notes users can bring up a "detailed and interactive" map of Chicago on the GamePad, and that off-TV play is also supported.
Original Story: Ubisoft Mexico may have let the Watch Dogs out a bit early, with a now-removed Facebook post pinning the game's Wii U release date for November 18. That's a Tuesday, the day of the week games are typically released in North America, and company CEO Yves Guillemot has already slated the Wii U version for November.
According to IGN's translation, the Facebook post noted that players can use the Wii U's GamePad as an interactive map of the game's Chicago setting, or simply as a controller.
As for what to expect from the open-world adventure on Wii U, we've yet to hear much. Back in March, Senior Producer Dominic Guay told Polygon that Ubisoft Romania was working on the Nintendo version independently, and looking at how to best incorporate the GamePad.
"We have our studio in Bucharest working on it, and we wanted that team to have the time to explore the GamePad and be able to have fun with it and see how far they could push it," Guay said. "It's also an interesting platform, because it has its own strength, which we want to take advantage of, and we didn't want to delay all the other platforms for that one. So we're going to take the time we need to make sure the game is good [technically] when we ship it and that it also, game design-wise, makes good use of the specifics of the Wii U."
Ubisoft released Watch Dogs for other consoles and PC back in May, having earlier delayed the Wii U version to "focus the team's resources where they could have the broadest possible benefit." Back in 2013, Ubisoft delayed Rayman Legends and expanded it to other platforms beyond Wii U, which Guillemot later revealed was due to concerns about sales. Last month, Guillemot said Watch Dogs would be "the only mature game" his company will publish for the platform going forward.
