Back when the Wii U was young, Activision supported the console by making it play host to its yearly Call of Duty franchise. The console launched with Black Ops 2 and a year later would get Call of Duty: Ghosts. However, last year's Call of Duty: Advanced Warfare didn't make the jump to the Wii U, which seemed to signal the end of the franchise's involvement with Nintendo's current home system.

However, the rumour mill is running at full capacity again this year. Activison has just teased the next entry in the series - Black Ops 3 - and the official Call of Duty website has seen an addition which appears to suggest that the new game could be making its way to the Wii U.

Allow us to explain a little. The Call of Duty site allows players to link their respective console's account. Last year, the site offered these options:

However, this year, an entry for Nintendo Network ID has made the cut:

Black Ops 3 will be coded by Treyarch - the developer responsible for bringing Black Ops 2 and Ghosts to the Wii U - and according to Activision is set in the future, like Advanced Warfare:

Call of Duty®: Black Ops 3 is the first title for next-gen hardware in the critically acclaimed Black Ops series. Developed by Treyarch, the award-winning creator of the two most-played games in Call of Duty® history. Call of Duty: Black Ops 3 deploys players into a dark, twisted future where a new breed of Black Ops soldier emerges and the lines are blurred between our own humanity and the technology we created to stay ahead, in a world where cutting-edge military robotics define warfare. With three unique game modes: Campaign, Multiplayer and Zombies, providing fans with the deepest and most ambitious Call of Duty ever.

Of course, we've been here before. Prior to launch there were rumours that Advanced Warfare was Wii U-bound, and that turned out not to be the case.

Do you think the addition of the Nintendo Network ID means that Black Ops 3 is coming to Wii U? Or could it merely be something that Activision is introducing across all of its dedicated game websites?
