So by looking at the chapter names it looks like Mashima is doing some sort of countdown. Chapter 483 was 7 stars, Chapter 484 was 6 monsters, and now Chapter 485 will be 5 Days Worth of food. Maybe something big will happen when it reaches one like Ankhseram reveal or Natsu becomes E.N.D to fight someone.
