China and Japan, let's say "Rest of the World".
PS Vita is getting God Eater 2: Rage Burst, a new version of the best sold game in Japan and it looks like Rage Burst could even sell more than the original game on the Vita. Games like Sword Art Online Lost Song, One Piece Pirate Warriors 3 and Persona 4: Dancing All Night will help the Vita a lot, the predecessor of them did all quite good on the Vita. And don't forget new games like Digimon Cyber Sleuth, SaGa and Night Cry which all have a lot potencial. "The Rest of the World" loves portable gaming, so Vita will sell a lot units there. I can even see Vita doing better in the west this year than last year, Sony must bring us a Minecraft bundle and localize games like God Eater 2: Rage Burst, Digimon Cyber Sleuth or the new SaGa.
Those big games that u listed, God Eater, Sword Art, One Piece, Persona, all belong to series that already have installments on Vita so there is a high chance that those games will sell well but not necessarily do a whole lot for hardware.
Can these even be called big games lol? God Eater 2 sold 440k...
