Video game development is a long and often arduous process filled with perils of different kinds. The best laid plans can sometimes never come to fruition, and it's often the case that a studio's original vision will change overtime, either because something doesn't work in practice, or because they've been given a strict deadline to meet.
Whereas in the past it would take developers going public for players to discover cut content, data miners now regularly uncover all sorts of juicy little secrets while going through a game's files, and discoveries are frequent.
