In December 2006, WSII announced that it reached an agreement with six owner-operators for teams based in Chicago, Dallas, Los Angeles, St. Louis, Washington, D.C., and a then-unnamed city. In September 2007, the launch was pushed back from Spring of 2008 to 2009 to avoid clashing with the 2007 Women's World Cup and the 2008 Summer Olympics and to ensure that all of the teams were fully prepared for long-term operations.
