It was June last year when EA decided to unveal the final cover for FIFA 13. But now they seem to hurry a little bit (probably they know what they failed by putting a buggy game like FIFA 13 on the market) and they want to get as many people as they can to buy their game.
Now, in April EA revealed it's not final artwork for FIFA 14.
Here it is:
It is pretty clear that FIFA will have for another year Messi on it's cover, which in my opinion is not bad since he still is the best player in the world (Cristiano Ronaldo fans should also note that the Real Madrid player is having a contract with Konami on promoting Pro Evolution Soccer).
The final cover should not be changed pretty much. We may see Lionel Messi's face in the final one and around two other players based on the region you are buying the game.
