Italy and Brasil will be in the Elite Eight. Italy always starts poorly. In 1982 they won the WC and deserved to be eliminated in the first stage. They always get the "extra help" from referees. Just like Brasil, Germany, and Argentina. Anyone has doubts of why are the winningnest teams? They are great competitors, and they have the benefit of the FIFA.
Look at Brasil today, they were worlds ahead Ivory Coast and they still got help with Luis Fabiano's double hand ball in second goal. Ericsson is a "turrible" coach, with so many quality players they have put together a miserable team play. They deserved to loose by 5. Then, after the referee make laughs with Luis Fabiano about his hand ball, he starts allowing Ivory Coast to play off limits and injure Elano. Make up calls... just "turrible".
The better game display I've seen in South Africa was Germany's first game. They didn't do well against Serbia (congrats Ederson) but I put them over Italy and Brasil to reach the final game. Argentina, Spain and England will be also in the Elite Eight, unless Spain and Brasil have to play in the last 16 game.
Uruguay and Holland will be tough to beat. Hopefully the quality of the games improve in the elimination games.
