World Cup qualified countries?

http://en.wikipedia.org/wiki/2014_FIFA_World_Cup#Qualified_teams

Japan are closest, only had to win or draw yesterday and they qualified, lost 2-1 though.

Argentina are pretty much there now, and Ecuador are pretty much nailed on as well. Probably need 3 points from last 5 games.

Asia; Japan have qualified at least for a play-off spot.
Africa is still early on, with the group winners playing off anyway so it's merely a guessing game.
North America group stage is wide open with all six able to fail or qualify yet in any order.
South America; Argentina are close but still a few games to go so rest is up for grabs.
Oceania; New Zealand have qualified for a playoff spot against a team from North America - the winner qualifies.
Europe; Germany and Netherlands are the only two with convincing group leads.
