This is a very possible situation. If India beat Australia (Which would be a little surprising, but then again it could very well happen, and West Indies beat England (probable) then Australia won't make the cut.
So basicly, this Australia/India game an almost be treated like a quarter final. It should decide who goes through.
So, comming up.
Tue 24 7th Match - South Africa v Sri Lanka
Must win for South Africa or they will be out! Doesn't matter for Sri Lanka, 2 wins and they have the highest NRR so it would take something unbelieveable to put them at third on the table.
I predict, Sri Lanka to win
Wed 25 8th Match - New Zealand v Pakistan
Must win for New Zealand or they will be out! Pakistan will want to win to get themselves a place in the finals.
I predict, New Zealand to win, though it is probably the toughest to call. Basicly only because of Pakistan missing players
Thu 26 9th Match - India v West Indies
Both with 1 win, so this game shouldn't be too important. India would want to win or else they may miss the cut with Australia and the West Indies going through. WI will be underdogs, but if they were to beat India then it would make India need to beat Australia.
I predict, India to win
Fri 27 10th Match - Pakistan v South Africa
If Pakistan win against NZ this match won't matter for them, if SA lose to Sri Lanka this match won't matter for them either. If Pakistan lose against NZ this match will be very important and they will need a good run rate.
I predict, South Africa to win, another toughie, this group is hard to pick. Same reason as before, Pakistan missing players. They did get the win early on, but having no Inzamam, Akhtar and Asif must show up somewhere. Surely!
Sat 28 11th Match - England v West Indies
Should be a easy win for West Indies. Though, if they were to lose it they could throw away a chance at the top 4.
I predict, West Indies to win
Sun 29 12th Match - India v Australia
Probably going to be the most important game, either both sides or just Australia will be fighting for a place in the top 4. Could come down to Australia needing a high run rate to be above the West Indies if they were to lose.
I predict, Australia to win
So as you can see, a lot of exciting cricket still to come. It is very close now. Each game will be pretty important. Lots of key matches. England are the only team totally out of it so far
