This question has been asked before, but it was for PS3 and Xbox 360 and was asked August 2010. This time around my question goes specifically to PS4, since I'm moving from Mexico to Europe and I was wondering if the European games will run in my console or if I'll have to buy a new one. I never thought of this before (which is why I never paid attention if it was mentioned in reports or specs of the console) and the research I did wasn't too helpful.
Generally, PS4 games will be region-free with 2 major points:
Now this is the same as it was with the PS3. Which according to wikipedia only had 1 region-locked game: Persona 4 Arena. It is therefore likely that no game makers would region-lock their game.
At this current time, I cannot find any region-locked PS4 games.
