Announced at Sony's pre-TGS conference, the first Yakuza game will be getting remastered for the PS3 and PS4 and called Yakuza Kiwami (or, by its actual Japanese title, Ryu Ga Gotoku Kiwami).
The upgrade will contain game systems featured within the most recent Yakuza 0. This will come out in Japan on Jan. 21, 2016, but of course, probably won't be announced for the West until after Yakuza 5 drops (if it's ever announced at all).
