Three old-school Sega fighting games, Virtua Fighter 2, Fighting Vipers, and Sonic the Fighters, may be making their way to the Xbox 360 soon, based on a trio of ratings from Germany's ratings board, the USK.

The three games, all originally released on Sega's Model 2 arcade hardware, were rated late last month by the Unterhaltungssoftware Selbstkontrolle for Xbox 360, though that doesn't rule out a multiplatform release. Sega has not officially announced re-releases of Virtua Fighter 2, Fighting Vipers, and Sonic the Fighters, but regularly has its downloadable game announcements leak early.

A release of those three games for digital platforms like Xbox Live Arcade and PlayStation Network would be in line with Sega's current strategy. Over the past two years, the company has released updated downloadable versions of Sega Saturn/Model 2 era games including Daytona USA, Guardian Heroes, and Nights Into Dreams.

Polygon has contacted Sega for details on the status of Virtua Fighter 2, Fighting Vipers, and Sonic the Fighters.
