«Prior to RWC 2007 the IRB stated that it would review the number of participating teams for future Rugby World Cups. […] The developing nations at Rugby World Cup 2007 have produced significantly enhanced performances since RWC 2003. […] Based on this […] the Council had no hesitation in approving the recommendation from the RWCL Board that 20 teams participate at the 2011 tournament.»
