In '06, each of the fours teams had to play three games in the first two rounds. Those with the top two records in each bracket ascended to the second round and the semifinals. If teams had identical records, a complicated formula of runs scored was used as the first tiebreaker.Next year, as soon as a team losses its second game in each of the first two rounds, it is eliminated. Once two teams have lost out, the other two move on to the next round. The semifinals remain as a single elimination competition to qualify for the finals. As far as the crossover goes, in '06 Cuba and the Dominican Republic emerged from one second-round bracket and Japan and Korea from the other. Those teams played each other in the semifinals, with Cuba ousting the Dominican and Japan vanquishing Korea. Japan defeated Cuba in the finals to win the tournament. That will change in '09, when the final game for each pool will determine seeding for the following round. Thus, in the semifinals, the winners of each pool in the second round will play the opposite pool's runner-up in the single-elimination games. In '06, then Korea would have played Cuba in one semifinal game, while the Dominican met Japan in the other. And who knows then what might have happened?
