Wow that is a long title. Well this news is a couple of days old, but I think it's being overshadowed by the Manhunt news. Here a quick trailer of FF on Wii. It's a foreign site and the video is right under SQUARE ENIX PARTY 2007. Near the end of the video you can see some ingame footage of a battle. Looks decent if you ask me.
