What I predict is an Indian win. When we take the history of Ricky Ponting's captaincy, in Sydney test, he was hungry for a single win, after which he din't mind losing one very badly!
So, as far as its concerned now, They've ended their winning streak in WC, so Ricky will not be as aggressive as he has been to Pakistan couple of nights before.
But, at the same time, its pretty difficult to predict the Australians in an ICC Event. Perfect example is the Champions Trophy 2009, where they won against Pakistan in last over with full of tension to secure Semi Final berth ahead of India. But in Semies and Finals, they out played England and New Zealand as easy as they could have a peg of beer.
What I smell is Australians bat first, score 250 or so. God of Cricket and King of Cricket will chase it in an easy note.
