The demo this year is basically the same as Fifa 12, the only differences I see are transfers, kits and a few more runs being made. Hopefully the full game will be different but I don't have much hope. EA have added a lot of new features, the new training mini-games, International management along with other major Career Mode updates, which makes me believe they have concentrated on the features rather than the game play which is kind of disappointing.
Regardless, I have pre-ordered and I won't be off this game for the next 12 months.
