Their E3 2013 games list lolUncharted 4. Boat and storm.
Square-Enix. FF only for PS4. We are not sure about this game, Square could show the game in TGS.
The Last Guardian: PS4 development. Wait for more footage this E3, maybe the next TGS.
Gran Turismo 6. In works in an early stage. I guess they are still not going to show the game this year. They have DriveClub and they must promote it.
