Square Enix claim they are considering making a Final Fantasy game for Wii U.
The unveiling of the Wii U seems to have piqued the interest of Square Enix. Producer Yoshinori Kitase has stated that “after seeing Wii U revealed at Nintendo’s conference, we are now considering the possibilities of bringing the Final Fantasy series to the format.”
This is obviously not official confirmation and if a Final Fantasy game is made for Wii U it probably won't see the light of day for a long time, even longer in Europe. However, as a Final Fantasy game of some sort is usually released on every console it's a fairly safe bet one will end up on Wii U.
