Its really cool that, as being Dutch myself, I see so many people here rooting for The Netherlands

We really have a very good team this year, much better than last years, so the poule fase won't be a problem (against Denmark, Cameroon and Japan) but they have to keep going so we dont get the same result as 2 years ago at the EC were we easily made it through the poule fase but got knocked out by Russia the next round..
This year, we have a team that can score with van Persie, Robben, Sneijder, Huntelaar, van Bommel (last 2 friendly games were 4-1 and 6-1), but the defense isn't that good so they have to make sure not to get to much goals against.
Robben's injury isn't that bad and he is going to South Africa but when he can play is uncertain, but I don't think we're gonna need him during poule fase
The Netherlands will probaby make it to the Quarterfinals, but then we'll get Brazil against us and although I really hope they'll win, I think its more likely that Brazil goes forth.
Spain has a very good team and as long as they don't suffer to much injuries among there players I see them win the entire tournament
Germany has a decent team, but not a team to win, they will probably make it to the half finals (beating Argentina in the quarter finals) only to lose to Spain
Argentina has a good team but Maradonna is not a coach so they won't make it past the quarterfinals because of poor coaching and bad relationships among the players/coach
France will suck. nothing more to say, there just bad
England will have to prove themselves again and with Rooney, Gerrard and Lampard they have some very good players who can score
So in short:
Spain over Brazil
