Eh? If anything it increases their chances, albeit for a shared hosting. Considering there are only a handful of countries who could single-handedly host a 48-team World Cup, it's almost guaranteed that they're going to start shooting for regionally-held tournaments (Belgium-Netherlands, South Korea-Japan, Scandinavia, etc.) A North America-hosted tournament split between the U.S., Mexico, and Canada is sure to happen, it's already been on the table for years.
