Electronics Arts isn't the only compnay to shy away from Wii U. Frostbite Engine 3 & Unreal Engine 4 is not going to touch the so called Wii U Touchpad. So games like Battlefield 4 or games made by Unreal Engine 4 will make it to Wii U. Only way you'll see Unreal Engine games being put onto the system is through other developers making games using Unreal Engine 3 to create unique and different games on Wii U.
