There might be a very small chance, considering that Black Ops 2 is on Wii U, but considering that Advanced Warfare skipped Wii U, I think it's a sign that the CoD series is done with the Wii U.
If it does get it, I don't think it'll get the DLC.
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
