Concacaf just released the 2022 qualifying method so good as time as any to start this thread.

So basically the top 6 teams by FIFA rankings go right to the Hex, no group stage. The top 3 automatically go to the World Cup.

The other 29 teams play in a completely separate group stage/knock out tournament. The winner of that will play the fourth place team from the Hex in a home and home. And the winner of that gets to play in the international home and home for the last World Cup spot.
