The World Championship is this summer. Sweden was supposed to host but couldn't raise the money so it's in Canton, Ohio at the Hall of Fame instead. To make it more competitive US players must meet some really strict requirements (can't be professional, must have graduated from college, can't be more than one year removed from college). Canada sends a weakened team too but that's because the CFL season overlaps the World Championships.
Group A features the traditionally strong teams and three of them advance to the semi-finals: USA, Canada, Mexico, Japan.
Group B features developing football countries and one team advances: Australia, Brazil, France, South Korea.
