Senior producer Dominic Guay said all the game's "core" social features - such as allowing users to access other players' worlds through smartphones - will be possible on the Nintendo platform.
"So the connectivity between players with mobile devices, the way you can control the city, the immersion, all those are core and on any platforms we're going to ship on we're going to make sure we nail those pillars down," he told Digital Spy.
While Wii U tablet features have been to be decided, Guay said that the game's themes of hacking with mobile devices is a "natural" fit for the controller.
"We're still investigating how we'll use the tablet on the Wii U, but with the things I mentioned before, for us it's not going to be a weird stretch," he said.
"It's natural. What's really cool with Watch Dogs, when we start thinking of those devices, it's not a weird abstraction, it's not like I'm a space alien and now I'm using a tablet. Why am I doing that?
"Aiden Pearce is using a device to control the city, so it's quite easy to imagine what we could do with that."

Guay has also discussed the improvements the PS4 version of Watch Dogs will receive, and what it's like developing for the next generation system.
Watch Dogs sees players take control of a hacker named Aiden Pearce, who has an entire city's surveillance system at his disposal. Aiden can tap into people's electronic devices to gather intelligence on them, and infiltrate security systems vital to the city.
The game will feature innovative social features that allow users to access other players' games using smartphones.
