The name is back.
Square Enix's "Fabula Nova Crystallis" has managed to return, and with a familiar name. According to VG24/7 citing Gematsu, the publisher has trademarked the title, "Final Fantasy Agito."
This is almost like a re-registration, as Square Enix registered "Final Fantasy Agito XIII" for the game that would eventually be called Final Fantasy Type-0 . This was a PSP game that launched in Japan but never saw the light of day in North America. Perhaps this new registration hints at a US release…? Well, there's no way to tell, but Square Enix is supposedly bringing Final Fantasy news to E3 in a few weeks. So maybe that's where we'll learn the truth about this new/old registration.
We usually get FF-related news at E3. It's just rarely what we want to hear.
