Wii U- Nintendo has not yet announced the Wii U’s price, and has said it’s not planning to do so at this year’s E3. Still, we know that the Gamepad and the Wii U won’t function without each other. Unlike Microsoft’s tablet integration, which will use a device you already have/purchase separately, you’ll be getting both the system and tablet when you pick up a Wii U.
SmartGlass- Since Microsoft has said SmartGlass can use the latest iOS, Android or Windows tablets and smartphones, most users already own a device that will be able to work with their Xbox 360. Given that, SmartGlass will likely be downloaded as an app. No app price has been announced, but we think it’s safe to assume it will be free, provided you have an Xbox Live Gold account.
