So Square Enix did keep their promise after all. Final Fantasy XV made an appearance at Tokyo Game Show 2014 in the form of a trailer for a demo to be released with Final Fantasy Type-0 HD in 2015.
The trailer features Noctis and gang traversing the world via their stylish convertible and beating up enemies together. From the looks of it, the game looks like it might be open world, and the gameplay footage also shows off battle mechanics such as double-teaming enemies with your allies.
Final Fantasy XV: Episode Duscae, which is the title of the demo, will be made available for players who purchase Final Fantasy Type-0 next March.
