Well my theory goes like this:
1.Aus has played in the last 3 world cup finals..in 1999 they played against pak(which is a Asian team)..in 2003 they played against Ind(which is a Asian team)..and in 2007 they played against SL(which is a Asian team)..so in 2011 they will again play against a Asian team!..only Asian team left is BD...so aus will play the 2011 WC final Against BD!
2.Ind(a Asian team) reached their
1st wc final in 1983 and won it...pak(a Asian team) reached their
1st wc final in 1992 and won it...SL(a Asian team) reached their
1st wc final in 1996 and won it..BD(a Asian team) when reaching their
1st wc final will win it..
if we Marge this 2 theories then it results that
BD will win the 2011 WC 
PS:
its just a funny theory..plz dont say i lost my head blah blah
