The draw takes places today in Doha at 19:00 (local time).
In my final draw post, I seeded the last 5 teams (that didn't play in the 2007 final tournament) using the March 2010 FIFA ranking, with Kuwait taking the last place in the third pot.
However, AFC have seeded them based on their performance in the 2007 AFC Asian Cup qualifiers: Jordan (10p), Syria (8p), Kuwait (4p), India (0p), Korea DPR (didn't participate).
Since these 5 teams didn't participate in the 2007 final tournament, I think it would have been better to seed them using the 2011 AFC Asian Cup qualifiers: Syria (14p), Kuwait (9p), Jordan (8p), Korea DPR (2010 AFC Challenge Cup winners), India (2008 AFC Challenge Cup winners).
