MGSV: The Phantom Pain (PS4)
Dragon Quest Heroes (PS4)
Will pre-order:
Tales of Zestiria (waiting for either PS4 port announcement or Collector's Edition)
Nobunaga's Ambition: Sphere of Influence (PS4)
Samurai Warriors 4-II (PS4)
Assassin's Creed: Syndicate (PS4)
Games with no release date that I will pre-order:
Final Fantasy XV (PS4)
Kingdom Hearts III (PS4)
Persona 5 (PS4)
Bravely Second (3DS)
Xenoblade Chronicles X (Wii U)
Maybe:
Star Wars Battlefront (I need to see more of it before I decide)
The Legend of Heroes: Trails of Cold Steel (I need to see more of it before I do)
I always pre-order, though. I know what I want and like what I like, so I see no negative to it. Pay it off as soon as it's announced and don't have to worry about it until release date.
