Lot of noises from various media sources on the topic this month, now Infantino is saying a scrapping of the 16 groups of three in favour of 12 groups of four is on the table: https://www.rte.ie/sport/world-cup-2...026-world-cup/
This would presumably mean the top two teams in the group progress, along with the best eight third-placed sides, similar to the current Euros format. That'll bring problems of its own, along with the mountain of games: we'd go from 64 in the current format to 80 in the standing format for 2026 to 104 under the proposed model. Only regional hosting could handle that really.
