We’ve known since early April of this year that One Piece: Pirate Warriors, the PS3 exclusive that did gangbusters numbers at retail in Japan, would also be coming to the west by way of the PlayStation Network. And now, thanks to Andriasang , we know that a new One Piece game is headed to another PlayStation device... though not the one you probably wanted.

According to Andriasang, One Piece: Romance Dawn – “a traditional RPG with a command battle system” – will come to PSP this winter in Japan. The game may very well be playable on the Vita as well, as chances are it will see both a retail UMD release as well as a digital release on PSN, but it’s certainly disconcerting to see yet another game that will sell big in Japan come to PSP instead of Vita, a fledgling handheld absolutely starving for content in its native country.There’s no word on if Namco Bandai intends on releasing One Piece: Romance Dawn outside of Japan, but with PSP’s flat sales in the west, it’s unlikely to happen. Then again, if One Piece: Pirate Warriors does well when it comes to PlayStation 3 later this year, then who knows?We’ve reached out to a Namco Bandai representative for official comment and will update when we hear back. In the meantime, let’s remain as confused as ever as to how Sony intends on selling PlayStation Vitas in Japan while letting its third parties continue to release big games on its previous generation handheld.
