Without being biase on my choices, I think most of the Affican nations a likely not going to make it past group stage. The few that would would likely get eliminated in the round of 16. Ghana most especially seems to have been placed in a group of death with Portugal, Uruguay and South Korea, no bad feelings but its game over. From the way I see it, they are the least in that group although, not to mind  the best doesn't always wins but most times, they do and this is world cup.

Anyway  if I'm to pick those I project to lift the trophy and other consolation prizes, I'll go with;
1. Germany
2. Belgium
3. Brazil
I'm sure they've got a few flaws but, that's my pick.
