Just read about this. They did this for the 2007 ODI World Cup, as well, where the much touted India v. Pakistan match ended up being an Ireland v. Bangladesh encounter. I'm not sure I agree with second round seedings being based on the last tournament's performance. Surely now that you have an idea of current form, you'd split them up based on first round performances.
Anyways, India, South Africa and England would be hoping for a Sri Lankan win today, and getting the Windies into their group instead of Australia. New Zealand and Sri Lanka seem to have a smooth path to the final, though, with Pakistan looking weak and Bangladesh or Ireland as the other team.
