At present Sky's 3D service is currently up and running in selected pubs around the country.
Sadly Sky has not secured the rights from Sony broadcast live matches in the UK. World Cup watchers in America will be able to watch live games in 3D on ESPN.
Sony will however be releasing a FIFA 3D World Cup Film, released on Blu Ray later in the year.
To find a pub near you showing the World Cup in 3D please use this website http://3d.sky.com/pubfinder/
