If you want to play the new FIFA expansion you will have to wait: FIFA 14 Ultimate Team World Cup was delayed.
UPDATE:
FIFA 14 Ultimate Team World Cup was released at May 30th.
A few hours before it was released the FIFA WC Kick Off mode.
FIFA 14 Ultimate Team World Cup Was Delayed
FIFA 14 Ultimate Team: World Cup, a separate mode within FIFA Ultimate Team (FUT), lets players build their ultimate squad of players from all 32 National Teams attending this summer’s tournament in Brazil. FUT World Cup features all 32 National Team crests, National Team kits, the official adidas® Brazuca match ball, the Estádio do Maracana, and all-new look and feel within FIFA 14 Ultimate Team.
Players can improve their team to make them tournament contenders by acquiring new players and consumables from special Packs in the FIFA 14 Ultimate Team: World Cup Store. Every FUT World Cup Pack includes a free Gold Pack available for use in the traditional FIFA 14 Ultimate Team experience.
It was expected to begin today, but FIFA 14 Ultimate Team World Cup was delayed in order to give time to EA Sports to fix some issues they have found it yesterday when they have released the update to some players.
Here is the official announcement made by EA Sports about this delay:
“Hello, FIFA fans.
To ensure the best possible experience, we have decided to delay the launch of FIFA 14 Ultimate Team: World Cup (PC/PS3/PS4/360/XB1) and the World Cup Kick-Off mode (XB1/PS4).
Knowing that our players have been so excited for these new modes made it a tough decision. However, as we progressed through final testing we encountered unforeseen issues that would affect all users who downloaded the update, so it’s important to address them first before release.
Our team is currently working hard to have the update ready to release in the coming days.
On Thursday evening (EU time) we will keep you updated on our progress.
– The FIFA Team“
