This year would mark the abolishment of the Challenge Round. The previous year`s champion would now play in all matches, rather than advance directly to the Challenge Round. The winner of the Inter-Zonal Zone would be declared the champion. 56 teams would enter the competition, 34 in the Europe Zone, 11 in the Americas Zone, and 11 in the Eastern Zone.
