I found this posted on a FIFA 06: RTWC for Xbox 360 messege board. Its not official but the posters logic behind the list of teams is very reasonable. Here it is.
Correction. There will be 72 international teams. I suppose that the 27 teams that are already qualified to the World Cup will definitely be on the game. They are:
Angola Cote d'Ivoire Sweden
Togo Costa Rica Serbia and Montenegro
Ghana Tunisia France
Japan Iran Argentina
Korea Republic Saudi Arabia Brazil
Germany Ukraine Ecuador
Netherlands Poland Paraguay
England Croatia Portugal
Italy USA Mexico
I also want to add that since the European and Intercontinental Playoffs are still to be played, they have to add those teams to the game as well, because FIFA 06 for Xbox 360 will be out a few days after the playoffs. Those teams are:
Trinidad and Tobago Bahrain Spain Slovakia
Uruguay Australia Norway Czech Republic
Turkey Switzerland
All these teams add up to 37. This means that there are 35 teams left. I have looked at the pictures for FIFA 06(xbox 360) and saw these teams:
Republic of Ireland Finland Cyprus Greece
Georgia Albania Armenia Andorra
Northern Ireland Belarus Scotland Romania
Nigeria Israel(not sure)
There are still 21 teams that are unknown. I think that it will be mostly European teams because of this quote from EAsports.com:
"Take part in the European Qualification rounds for the World Cup or create your own custom tournaments...1,700 players in nine different stadiums from Europe and the rest of the world." Obviously there will be a European preference, but i think that the game should also have Central American teams in it, not that I'm Central American, but it is unfair for there to be so many European teams and so little Latin American teams or from any other part of the world.
