They are all groups of death.
Group 1 Australia Japan Uzbekistan Bahrain Qatar
In the last round, Qatar beat Iraq and Bahrain beat Japan. Finishing top two will be a mean feat and even top 3 commendable (for the playoff v New Zealand (or other Oceania?). Japan v Australia is always going to be close.
Group 2 South Korea Iran Saudi Arabia United Arab Emirates North Korea.
South Korea and North Korea couldn't be separated and that match up guarantees virtually no one will see the games - in the last round North Korea's refusal to recognize the South's national symbols saw games played on neutral ground (the two countries plus the USA are still at war - since the 1950s). UAE and Saudi have the climate advantage.
Overall, the Asian confederation will have a climate advantage over the European teams in Africa 2010 - let's hope its us.
