The number one thing I want is an easy way to transfer Pokemon to one game. I have Pokemon spread across three different DS carts, some that are over 10 years old from RS transfers. They should make some Pokemon box app for Wii U, and use the wifi function to transfer over the Pokemon and into X Y. DO THIS NINTENDO.
Speaking of which, I would like a battle stadium game for the wiiu, but with a story that's in an entirely separate mode.
