Last year, Sega announced that it would be remastering the PS3 Yakuza entries for release on PS4. The idea was to have each game playable on a single console and series producer Toshihiro Nagoshi even commented they were being done for "new overseas fans."
At E3 this year, I had a chance to speak with Ryu Ga Gotoku Studio's Kazuki Hosokawa -- director of Yakuza 5 and 0 --and I asked whether or not the west would receive the recent PS4 ports of Yakuza 3, 4 and 5. While there wasn't much he could say, he did tell me, "It's better not to say anything at this time." That's a bit of a bummer, but it doesn't deny that Sega is thinking about the possibility.
Another question I brought up is if a PC port of Judgmentwas on the table. Some recent comments have made it seem likely and with Yakuza now having a home on Steam, one could assume that Judgment will soon follow. Hosokawa told me, "There are no concrete plans as of yet, but we're always looking into different platforms and considering, so it's on our minds for sure." Again, that doesn't deny the possibility, but there's likely nothing Hosokawa can say on the matter. I wouldn't give up hope for these titles, but Ryu Ga Gotoku Studios is more focused on getting Judgment out in the west and finishing development on Shin Ryu Ga Gotoku.
