E3 insider lists Call of Duty: Advanced Warfare for Wii U

[Never]

Until Activision start releasing games on the eshop, as far as I'm concerned Activision don't make Wii U games. As someone who's not played many COD games I wouldn't might playing one every five years or so and if a well received iteration came out on Wii U eshop I'd probably think it's due.
