According to Ryokutya, the latest Dengeki PlayStation reveals that Yakuza 3 through 5 will be released on PlayStation 4 as remasters with better resolutions and frame rates. In the magazine article, Sega has also outlined the release schedule of these remasters in Japan as follows:
- Yakuza 3: Coming on August 9, 2018. Priced at 3,990 yen, comes with a serial code to download the soundtrack.
- Yakuza 4: Coming in Fall 2018
- Yakuza 5: Coming in Spring 2019
Note that all dates mentioned above are for the Japanese version releases. As this news is still very fresh even in Japan, we don't know yet on when they will be released in the West.
With the first and second games' Kiwami remakes, as well as the prequel Yakuza 0 and the latest game Yakuza 6 already available (note that Kiwami 2's Western release is slated for August 28), this marks that all of the 7 mainline Yakuza games that tell Kazuma Kiryu's story will be eventually playable on the PlayStation 4.
