Complex: "Call of Duty is coming to a Nintendo console. We don't mean some watered-down, half-assed version with waggle and point-to-aim controls. With Call of Duty: Black Ops 2 on the Wii U, we're talking about a bonafide, honest-to-goodness, fully-featured CoD game. The Wii U's GamePad controller has all the buttons that a PS3 or Xbox 360 controller has, plus that big, beautiful touch screen. So while every in-game function is performed just like it would be on the other consoles—you'll get used to it quickly—the touch screen allows a few extra 'perks.'"
Almost all of those reasons could of been combined into one,basically the mini/map and menu is on the game pad....
Don't forget sweet dual screen multiplayer and more control methods. They didn't mention it but im pretty sure you can still play with wiimotes although most people probably don't care about that. (I actually like IR for FPSs it works well and I like that I'm physically aiming at things)
It still uses IR i.e. wiimotes for aiming, thank god ! That is confirmed by Treyarch. I'll still try learn dual analogs, but...meh... :)
if i hads the wiiu reserved this mights interest me. PS3 or 360 for nows.
