Localization on the Yakuza franchise outside of Japan has stalled, and despite its popularity, it is becoming growingly unlikely that Sega will opt to work on Yakuza 5 or beyond. To date we are two games behind the Japanese, with Yakuza 5 (PS3) and Yakuza:Ishin (PS3/PS4) being released between December 2012 and February 2014.
As of possibly next year we could be another game behind, with Sega and Studio Yakuza confirming development of their next game in the franchise – Ryu Ga Gotoku: Zero / Yakuza Zero. Details are currently limited, but expect to hear more on this game during TGS 2014 next month.
It should come as no surprise to anyone that the game will support both PlayStation 3 and PlayStation 4 consoles.
