For me both T20 WC and ODI WC are equal..if not T20 WC is slighty ahead at the moment. I mean there are so many contenders and it is a really big thing if you manage to win it once...because it's always damn close. On the other hand you can predict the ODI WC far easier..I hope the ODI WC 2011 will be different. The history and the more testing of the players makes the ODI WC more important though..
