My pick is that it will either be an Aust (beat Arg) v USA (beat Neth) or it will be a more traditional WC clash of Arg v Neth instead.
Personally, I think the world is ready for a world first of seeing Australia V USA.
There has been a few USA v NZ and Aust V Canada (brawls

) matches, but I don't ever remember an Aust v USA.
I bet Aust chokes for the USA like a Boxing dive.
Japan def Croatia (here's hoping for a refreshing Qatar WC)
Portugal def Brazil (Brazil are a bunch of Wankers)
England def Senegal
France def Poland
Morocco def Spain.
It seems that playing the 'Soccer' World Cup in New Nations does affect the outcome of the usual winners.
My psychic powers tell me that it will be England def Brazil in the WC Final.
...thanks to its two colonies USA & Aust doing well.
