Amazon might have done it again as they have mistakenly unveiled a game named Dissidia Final Fantasy NT for Playstation 4. If you can remember, the website also leaked Darksiders 3 in the past so yeah, you can expect that this Dissidia Final Fantasy NT is legit and I'm betting Square Enix will officially announce it on E3.
Initially, the store advanced with the listing of Dissidia Final Fantasy NT, the PS4 version, which despite not having an associated release date, revealed many of the features as well as the first trailer.
There are no particular details on Dissidia Final Fantasy NT for PlayStation 4, the game would include a roster composed of 20 characters, where Noctis is included. It also speaks of a written plot by Kazushige Nojima (Fantasy VII Remake, Final Fantasy XV, Final Fantasy X, Kingdom Hearts, Kingdom Hearts II) and a combat system rebalanced than the arcade version.
The product page on Amazon.com also includes a temporary cover and a release date placeholder (31 December 2017). In all likelihood the announcement of Dissidia Final Fantasy NT will happen at E3 in Los Angeles, so we have to wait for official confirmation or denial by the publisher Square Enix.
