This was on Dualshockers last year:

Also this may or may not mean anything:
http://www.gamespot.com/forums/system-wars-314159282/level-5-announces-dark-cloud-3-for-playstation-4-29374991/
It's a gamespot forum thread and the source link doesn't go anywhere, but if it's in any way correct then it means the Level 5 PS4 game is very likely a Dark Chronicle game.
By the sounds of things Level 5 weren't happy with the reception of White Knight Chronicle and they aren't involved in Ni No Kuni.
Take it with a pinch of salt, but it all seems to fit nicely together.
