FF7 Remake Definitely Getting.
FFXV
KH3
Persona 5

Haven't played a Star Ocean game before but looking at SO5 with intrigue.

Dragon Quest XI is also a possibility.

Edit: Almost forgot about Dissidia PS4 and Nier Automata, damn that game looks good.

For now
FF15. This game needs to come as soon as possibe. Even my wife that's not a gamer ask me if the game finally released and I was shocked and told her not yet. she realized I have been waiting for a ling time now.

DQXI
Persona 5

These are my top 3 at the moment

Probably all of those but I need to look up a few of 'em.

Well I'm a huge JRPG fan, it's my favorite genre, but I will be buying almost to many to list. So instead I'll just put down the games that make me want a PS4.

Persona 5 (this is mostly why, Atlus is my favorite company)
Final Fantasy 15
Star Ocean 5

Ys 8, Dragon Quest XI, and Persona 5 (will be my first Persona if I don't play P4 Golden on my Vita first).

Always loved JRPGs but I drifted away during the PS3 era.  I think now is a fine time to return to getting more than just the usual suspects.

I will buy every game you listed, with special emphasis on Kingdom Hearts. c:

I will also buy some you didn't list.

JRPG heaven~

Dark Souls III
;)

XV for now. I'll see about the rest and whether they meet current gen standards.

There's going to be prequel elements in Kingdom Hearts 3?

Valkyria Azure Revolution and Tales of Berseria
