For those wondering...

It's getting a PS4 release in order to satiate console FF fans hunger for FF titles since XV is still a little ways off and to test the waters for XV's release. The other reason is that the game's director Tabata has been co-directing XV and apparently more knowledgeable about the PS4 schematics and thus it was a smoother transition due to this.

Frankly, I'm just happy it's getting released over here finally. I only feel bad because the game will probably be like Brave Fencer Musashi, a good game only remembered as "that game that came with the FF demo". So far I think only DQVIII has escaped that trap.
