I've generated the results for the 491 matches between now and 15 October 2013. I'm well aware actual results could be wildly different. Another thing to take into account: teams will most likely scheduled friendlies for the remaining available FIFA dates and this will affect their final ranking.
The outcome could be a bit suprising for some.
Groups D, I and J in Africa and group G in UEFA seem set for a photo finish, while Uzbekistan look destined to make their World Cup debut.
Here's the breakdown by confederation:
Korea Republic and Japan as group winners, Uzbekistan and Australia as runners-up. Play-off between Iran and Jordan to decide who will meet Uruguay.
Group winners: South Africa (A), Tunisia (B), Côte d'Ivoire (C), Zambia / Ghana (D), Burkina Faso (E), Nigeria (F), Egypt (G), Mali (H), Libya/Cameroon (I), Senegal/Uganda (J).
The draw mechanics for the next round are not known yet.
Direct qualification: Mexico, USA, Honduras. Costa Rica to meet New Zealand in the play-offs.
Direct qualification: Argentina, Colombia, Ecuador, Chile. Uruguay to meet Iran/Jordan in the play-offs.
New Zealand to meet Costa Rica in the play-offs.
Direct qualification: Croatia, Italy, Germany, Netherlands, Switzerland, Russia, Bosnia-Herzegovina / Greece, England, Spain.
This is how it looks for the UEFA play-off (if the seeding is done using the October FIFA ranking):
Pot A: Portugal (7), Greece (13) / Bosnia-Herzegovina (16), Belgium (14), Sweden (16)
Pot B: Romania (22), France (24), Norway (25), Poland (37)
Czech Republic out as worst runners-up.
Greece / Bosnia-Herzegovina are both displayed because according to the generated results, they will both finish with 26 points and it will go down to goal difference. Bosnia-Herzegovina (GD +13) currently have the upper hand, Greece's GD being only +4.
This is the top 30 of the October 2013 ranking based those generated results:
The seeded teams would be: Brazil, Spain, Croatia, Argentina, Colombia, Netherlands, Germany and one of Portugal or Mexico.
Based on the generated results, Portugal will be involved in the play-offs. If they don't make it, Mexico would be seeded.
