How long can the Final Fantasy numbers keep up?

I think I alone bring enough revenues for Square Enix to keep the Final Fantasy series alive forever and ever after.

My pre-orders:
Lightning Returns: Final Fantasy XIII
Lightning Returns: Final Fantasy XIII (Collector's Edition)
Final Fantasy X | X-2 HD Remaster
Final Fantasy X | X-2 HD Remaster (Limited Edition)
Final Fantasy XV

Bonus: Bravely Default + Drakengard 3

Dont support SE on LR - FFXIII they need to know they fucked up
