We know it’s going to happen soon enough. The 12-team playoff will expand to 14 or 16 schools, and probably 24 or 32 after that.
It’s happened before. Prior to 2000, college football fans just accepted that there could be multiple national champions, as unthinkable as that is now. Anyone older than a current college student remembers the two-team BCS, which begat the four-team CFP, which in turn led to our current 12-team version.
On its face, expansion just makes sense. More playoff schools mean more interest in the playoffs, which in turn means more broadcast, ticket and donor revenue all the way around.
