It appears Square Enix has another Final Fantasy spinoff in the works. By searching Europes trademark database, we discovered Final Fantasy Type-0.
In addition to a trademark for a potential title, Square Enix filed a logo for Type-0 with "type zero" written in kanji. Usually, Square Enix just files a title like Nier or Tactics Ogre. Since Square Enix registered a logo too, this is probably bigger.
Square Enixs 1st production press conference is just a month away. Perhaps, well see Final Fantasy Type-0 popup there.
