EA Sports community manager Rob Hodson has posted an update on the release of FIFA 14: Ultimate Team - World Cup 2014, which was meant to hit the back of the net on Xbox One and PS4 yesterday.
"Xbox One: Update live, Kick-off available, online unavailable. | 360 Update live, no menu change until online is available."
Still no word on the Playstation version, although Joe tested it and reported that while you can play a World Cup match, you are currently unable to access the Ultimate Team mode.
UPDATE - The EA Sports FIFA account has posted that the update should be live for Playstation consoles as well.
