Grand Theft Auto: Vice City and Grand Theft Auto: San Andreas are both listed by the Entertainment Software Ratings Board for a release on PlayStation 3 in North America.
While neither listing specifies what the releases will entail, it is likely that both will be made available as downloadable PlayStation Network titles in the vein of the Grand Theft Auto III PSN port.
This follows Rockstar's announcement last week that it would be bringing the 10-year-old Grand Theft Auto: Vice City to iOS and Android. Grand Theft Auto: Vice City first released in 2002 for PlayStation 2, and was later made available for the Xbox and PC. Grand Theft Auto: San Andreas released in 2004 on PlayStation 2 and has since been released for the Xbox and PC.
