Sony's Gio Corsi says that in addition to five new characters and six brand new stages, Ultra Street Fighter IV for PS4 will include all previously released costume DLC.
This includes the recently released Vacation and Wild costumes. Also included with the package is the Omega Mode, which you can learn more about by watching this trailer.
These various bonuses combine to make the PS4 version of Ultra Street Fighter IV "the ultimate" edition of the game, Sony says. Ultra Street Fighter IV is already available for PlayStation 3, Xbox 360, and PC. An Xbox One version of the game has not been announced.
The PS4 edition of Ultra Street Fighter IV was originally announced in December and is due to launch sometime this spring. Pricing has not been announced.
