Performance seems pretty bad in the open areas, unfortunately. While I love the way the game looks, the other PS4 Yakuzas just look so good running at 60 that it's going to be tough going down to 20-something with tearing. I'll gladly buy it day one if it gets localised, but I do hope they can do something with patches, at least on the Pro.
God, I almost want to import this, but my Japanese is nowhere near good enough yet. If we don't get a localisation announcement at PSX I'm going to riot.
