I remember when the console was released people were debating whether it was going to have problems playing North American Blu Rays and game discs. Any issues playing any discs from this region?
It's locked to region B. You can't play domestic blu ray movies. PS4 games are region-free so that's a non-issue. However, you can change a PS4 region code I believe 3 times in it's lifetime before it becomes locked to that region for good. So you could buy it, and then change it to region A if you want to. There's a settings modification.
So no, no multi-regional playback. But you can set it to one region you want.
