Fifa 14 was unveiled in April 17. That day, Electronic Arts only talked about Playstation 3, Xbox 360 and PC versions.
Today, Amazon US has listed Fifa 14 for PS Vita with a price and a release date. EA did not give a release date last week when the game was fully presented.
This info has been deleted from the website, but only a few hours ago we could see that Fifa 14 for PS Vita would cost 40$ and September 24 set as the release date.
Update: Other retailers are also listing PS2 and PSP versions of the game.
