So after Italy's loss to Canada, I think we can fairly say that the Final 6 participants are confirmed: Brazil, Iran, Russia, France, Poland + USA
RUS can lose to ARG but they still end up with 11-4
Same with FRA can lose to BRA and still end up with 11-4
POL will win the next 2 remaining matches and have 11-4 record
So the Final 6 are roughly the same like last year, except for one: Iran (who took Serbia's spot)
