The makers of Final Fantasy 13 for the 360/PS3 are creating a wii exclusive game called Full Metal Alchemist Prince of the Dawn. The scenario of the game is completely original, and is also tied into the anime series. They are also creating a new character who will feature heavily in the game. It will release in Japan later this summer, and nothing has been announced about overseas releases just yet. More details should be released soon.
