No, these count as normal matches (this is one round). The next and last round will be quarterfinals, semi-finals and the final + match for third. That way every round will consist of 16 matches. This way the points per round stay fair.
You can get extra points for this, but those can only be achieved by the predictions you made before the WC started. The rounds after groupstage you predicted then are worth points now if they were predicted right. So in a way you can get more points for them.

Mulva, you were allowed to predict the matches I gave you now. I can count those other matches like that if you want. You are still allowed to predict the remaining games.
