In the main series, not including sequels/prequels and MMOs, they have released just one single player numbered game in in six years.  I believe these other XIII sequels/spinoffs are being made to get an understanding of the modern gamer and what they can do to please people.  I think that once they have a better understanding, they will start to really push on a new game.  By using XIII sequels/prequels, they can minimise costs that would be spent on concepts, design and development for monsters, worlds, lore, characters which they would have had to pay a lot for if they were to come up with a completely new game.
