Several people have added their honed judgements/wild guesses to the comments at the bottom of the World Wheelchair Qualifying Tournament post.
Add yours, and if you include your name you can bask in glory when you're proven right.
Here's links to the last Qualifying tournament, Prague 2008, the 2009 Worlds, and the 2010 Paralympics.
2008 was the year Germany qualified and went on to win a bronze medal at the 2009 Worlds after leading the round robin all week.
It was also the year China emerged on the world stage. They performed creditably at the 2009 Worlds, tying for 5th in the round robin, and 8th post-tie break. That's normally good enough to return at the following championship, but with 2011 host Czech Republic taking a slot, the bottom three teams rather than the bottom two at the 2009 Worlds had to re-qualify.
