I laughed reading that statement and that is highly unlikely to happen.
FIFA itself has certain reasons and objectives with a schedule that is held every four years and this decision cannot be changed arbitrarily.
If the initial provisions have gone well and smoothly, there is no need to change them because they may require changes in their entirety.
World Cup every two years sounds funny more than anything, the only reason why many teams try hard for the world cup is being every four years and this can make the world cup tournament very important but being every two years can change everything. Also, this won't suit the FIFA calendar to have a world cup every two years instead of four.

FIFA has worked well for every World Cup event and this success is also supported by careful planning so that we just accept whatever has become FIFA rules and policies.
