The Yakuza Collection is today complete

Sega have announced that the Yakuza Collection, is out now in stores, giving PlayStation 4 players access to Yakuza 3, 4 and 5, with Yakuza 5 also arriving digitally, completing the trilogy on the digital front.

The Yakuza Remastered Collection is far from a typical console generation port. In addition to graphical and performance upgrades (720p>1080p at 30>60fps), all three games have gone through a rigorous re-localization process. The English scripts for each game have been reviewed, revised, and even rewritten in some cases, and content previously cut from the Western releases of Yakuza 3, 4, and 5 have been re-added in The Yakuza Remastered Collection.

If you want to go the physical route, you can pick it up here for yourself.
