I choose Wii because

1. The Wii is cheap and I have a huge chance of getting one right now.
2. Nintendo and Square-Enix have known each other for a while (kind of) and can try to put it up for Wii.
3. If it was to come out for PS3 or Xbox 360 the PS3 is way too expensive that even some Final Fantasy fanboys won't even buy it. Then the 360 nobody really likes and once they beat this game then there going to have to wait for about another year just to get Final Fantasy XIV. Putting it on the PS2 would also be nice to do.
