They've got three years to figure it out, so they're probably just throwing stuff against the wall at this point, but is anyone else wondering how on earth they plan to fit in a 2021-22 Nations League around World Cup qualifying and the '21 Gold Cup? Because they've stated that both the '21 Gold Cup and '21-22 Nations League are happening, as of now, and World Cup qualifying is obviously also happening. Unless the Nations League is now World Cup qualifying (which would be weird, because you've now eliminated everybody not in League A from World Cup consideration before you've even started), I don't see how it's possible.
I wonder when the World Cup 2022 qualifying format will be announced. The first description of the five round format CONCACAF used for World Cup 2018 came out in September 2014.
