Virtua Fighter 5 Ultimate Showdown just launched as a PlayStation exclusive, but it may not stay a PlayStation exclusive for long. When Lost Judgment was announced, fans saw that the website showed a Steam version of the game was coming before it was promptly taken down. Now history has repeated for Virtua Fighter 5 Ultimate Showdown in a big way.
Looking at the website code, one can find that there are images for the Switch, Steam, PlayStation 5, Xbox One and Xbox Series S|X. Sega always says they want their their games on as many platforms as possible going forward, so its possible the game is just a timed PS4 exclusive.
