If I had to make a prediction, I'd say:

Spain - but might collapse under pressure
Brazil - duh
Italy - god forbid
Germany - tournament players par excellence, even when they are bad, they make it to final
England - why not, eh? Capello's got his act together
Serbia - surprise package

France is really just waiting for Blanc to take over. The ref will finish the blues off in the last group match against the home country.
Argentina's players are second to few, but they are coached by the Nose of Coke, El Diego. who managed to not select half of Inter's side.

Portugal and Holland for dangerous outsider.
