They even made unique DS and Wii versions of their CoDs; you will see BLOPS2 on Wii U
Call of Duty®: Black Ops 2 propels players into a near future, 21st Century Cold War, where technology and weapons have converged to create a new generation of warfare.”
+ screenshots about the drones
+ people interested in defense technology evolutions/what we can expect for future military equipments know how it's heavily related to camera (personal drones, mini-camera on the back for extended field of view, two-movable-parts weapons to fire behind walls without exposing you thanks to a camera on its front, etc.), drones, etc.
If Activision is really serious & motivated in taking advantage of the Wii U features, we could have the absolute version in terms of gameplay & above all, fun.
Edit: Yeah, Yeah, Activision, i've spent so much time on MW & BF, i know the difference, but believe me, when i saw these screenshots, i thought about EA Command & Conquer Generals 2, with the drones (similar to USA faction drones on Generals 1, it really looks like a US soldier supported by vehicles battle drones), the setting (near future with advanced weapons but not too futuristic), etc :/
