The governing body has previously indicated it would cut the number of competing teams from 14 to 10 for the 2015 tournament, with ICC associate member countries such as Canada and Kenya likely to suffer from such a move.
The format of this year's World Cup has been criticised for being too long, with India's triumph against Sri Lanka in the final on Saturday arriving six weeks after the team opened the tournament against fellow competition co-host Bangladesh.
"The length of 50 overs will find certain teams out but I think there are 10 teams that can seriously compete in that format," ICC chief executive officer Haroon Lorgat told Sky Sports News.
"That's a debate we are still finalising; in fact the board meeting over the next two days will consider that and will determine which teams will play in the 2015 World Cup," Lorgat added. The ICC currently has 10 full member nations with Zimbabwe the only of those who is not a Test-playing country.
