I would have gladly bet against anyone who told me that the World Champions would be ranked dead last half-way through the tournament.
Technically, Pakistan or England have a small chance of making the semi-finals by winning all of their remaining matches. However, they both can't make it together because they'll face each other next month. Given their miserable form, it's highly likely that the semi-finalists will be India, New Zealand, South Africa, and Australia.
A New Zealand vs. South Africa final would be spectacular as we would get a totally new World Champion. The Kiwis will have definitely earned that one.
