Denmark, Switzerland, Armenia and Poland are countries that a few years ago expressed interest in participating in future tournaments. Denmark and Poland have left FIB, while Switzerland debuted in the 2019 edition, as did Great Britain. Armenia wished to participate in the 2011, but was not allowed to, as the tournament format at the time only allowed twelve teams and several more wanted to come. Of the countries which still have not taken part, India was also denied in 2011. Most probably also Lithuania. The reason for the 2011 tournament having only eleven teams, was a late cancellation from Australia, another country no longer an FIB member.
