This, according to Sony Pictures CEO Tony Vinciquerra, who said their current slate is "just the beginning" (although he didn't mention the Final Fantasy project), and that they were currently working on 7 TV shows and 3 movies based on their video game properties.
"We're also really thrilled to bring some of the best PlayStation IP to new media like film and television... This is just the beginning of the expansion of our storytelling into new media and even wider audiences. Sony is a creative entertainment company, and entertainment has never been more important."
While video games and TV/movies used to be a toxic combination, the alchemy has since been figured out with shows like The Witcher (@ me mofos) and Castlevania, so the idea of a studio being more invested in making their IP's do more work for them makes a lot of sense.
That said, we don't know a darn thing beyond this, so... I guess we'll just have to wait and see what's announced next.
