The Game Rating and Administration Committee of Korea has rated (via @Xenosaga7) Virtua Fighter 5 Ultimate Showdown for PS4. Virtua Fighter 5 Ultimate Showdown is yet to be officially revealed by Sega but the rating mentions Virtua Fighter esports as the original title. Back in September last year, Sega announced a Virtua Fighter esports project with more information to be revealed in the future. Going by the rating, the project includes Virtua Fighter 5 Ultimate Showdown on PS4. Watch the Virtua Fighter esports project teaser trailer below:

Virtua Fighter 5 is currently playable natively on PS4 only through Yakuza games while Xbox One (and Xbox Series X|S) owners can play Virtua Fighter 5 Final Showdown through Xbox Backward Compatibility. Final Showdown released back in 2010 and is an updated version of Virtua Fighter 5 that released in 2006.

Hopefully Sega reveals this project soon. As of now, Virtua Fighter 5 Final Showdown is available on PS3 and Xbox platforms.
