SCEE: Dreams, Persona 5, FF7 Remake coming 2016, No Man's Sky TBA

[Burek]

Looking at that list, TBA 2016 just basically means that they have no idea at all.
Dead Island 2 is definitely 2016 game, and neither is FFVII most likely. And given the fact that every single 1st party exclusive after launch.got delayed, I expect Horizon to drop to 2017 as well.
