World cups are going to be slightly easier to reach from now on, with 48 teams going, so some of the times we *almost* made it, we might now start actually going.
So perhaps one in every 3 or so world cups rather than every 64 years.
Also it is possible that this level of success we have had means that more kids are getting into football instead of rugby or other sports, and that might lead to more success in the future.
