Esports World Cup 2024 (August 14th to 18th) has announced the groups

"Knockout Bracket: 13 players from the Main Stage and 2 players from the Qualifiers"

so Shin and Showtime will be in the knockout bracket, I'm guessing top left and bottom left of the bracket

so the top 4 will be made up of the 1st place from each group, the winner between the 2nd place from each group (with the loser going to the knockout bracket), and the last slot is the winner of the knockout bracket
