Tecmo Koei is bringing an enhanced version of Warriors Orochi 3 to PlayStation Vita and PlayStation 3. Warriors Orochi 3 Ultimate has 1.8x the amount of story content as the original release and a bunch of new characters like Sophitia from the Soulcalibur series.
If you have Warriors Orochi 3 you can import save data and any DLC you purchased into Warriors Orochi 3 Ultimate. Save data from the PSP version can be imported into the Vita release. Save data importing is done over PlayStation Network. Also, if you saw the good ending on your file you can jump straight into the new story.
Warriors Orochi 3 Ultimate is slated for release on September 26 for PS3 and Vita.
