Maybe Activision is testing the waters to find out if there's actually enough of an audience on Wii U now who could potentially buy their game. if there's enough of a buzz about a Wii U Version Activision might think about producing such a version.
If so, I don't think however this would already happen for this one, it's more probable then we're talking about next year's CoD
Edit:
Or they want to to make a quick port of a PS360 Version to compensate for their falling sales
