From the first few matches in the African zone, I'd not be too sure about the teams you've listed; I also have doubts about a couple of the European teams - they can be so unpredictable at times.
As for the Oceanian region, I feel that it will once again fail to make a world cup appearance.
In the Asian region, I'm not so sure about Iran.
From North America, Canada will definitely not qualify.
From the South, I wouldn't rule out Bolivia and Peru - you never know.
However, I do agree that yours is the most likely group.
