I have taken this from World Squash Federation, but I think they only choose one from the five!-

Squash received a major boost today (Tuesday) with the confirmation that the sport has been approved by the International Olympic Committee (IOC) as one of five Recognised Federations that should be "studied further" with a view to inclusion in the Olympic Games programme for 2012.

The IOC is assessing the merits of all the sports and disciplines that were on the programme of the Athens Games, plus the five selected Recognised Sports: Golf, Rugby, Roller Sports, Karate and Squash. The final decision on the Olympic Programme for 2012 will be taken in July 2005.

The final decision to choose 2 sports on 5 will be taken in july, by the National Olympic Comite elected to organise olympic games. If rugby is choosen, it will be played by 7 players.

The decision will be taken by the IOC members, not the National Olympic Committee which hosts the games. There will be no new sports included unless one of the current 28 is dropped. There are five new sports being considered but npossibly one of them may get in.
