SEGA is getting ready to reveal another Yakuza title, as evidenced by a new teaser site that appeared at Ryu-Ga-Gotoku which is the Japanese name for the title. There isn’t much on the site except for the game’s logo on a red background and an August 24th date for the reveal. This could be anything from Yakuza 6, Yakuza Ishin 2, Yakuza Dead Souls 2, or a completely different branch for the franchise.
Considering that neither Yazkuza 5 or Ishin have been localised for Western audiences we may be waiting quite some time before this new Yakuza hits our shores. This title is expected for both PS4 and PS3. Still we could get a localisation announcement around the same time, which is based more on hope than any fact.

Given the industries current trend it’ll be Yakuza 1 remastered.

Actually, there was talk of a Yakuza HD collection at one stage, so you might not be far off!
