I got the PS4 and I've been doing "research" playing Until Dawn. Very well made, the kind of game I like (and probably very similar, of course on a MUCH bigger scale, to the games I make).
However I must say that looking at the other PS4 exclusives... there's nothing that I can't get on PC, but at cheaper cost. Of course you need a powerful PC, but my setup is not even very good and I can play GTA V just fine.
I will probably get Persona 5 and the new David Cage game, and then not sure if I'll touch the PS4 again
