A few days ago in the pages of the Japanese magazine Famitsu, Hajime Tabata declared that a unprecedented final cutscene will be present in Final Fantasy Type-0 HD, which was never included in the PSP version of 2011.
This video was recently published on the Internet, therefore containing spoilers while the game is not yet marketed on PS4 and Xbox One.
This extract tends to confirm that Square Enix will probably present itself as a suite entitled Final Fantasy Type-1. Note also that the Japanese publisher reserved the Final Fantasy Type-1, Type-2 and Type-3 domain names in 2011.
Now remains to be seen when Square Enix will want to say more about the rest of its Japanese RPG. Recall that Final Fantasy Type-0 HD will be released on March 20, 2015 on PS4 and Xbox One, and will include a download code for the playable demo of Final Fantasy XV in its Day One edition.
