Muramasa Rebirth is definitely crossing the sea, we just don't know when.
Released in 2009 for the Wii, Muramasa: The Demon Blade stands amongst the best-looking 2D games to date. But despite a warm critical response, the game's limited release and complete lack of promotion led to disappointing sales and yet another "cult-classic" for the 2D maestros at Vanillaware. The studio is looking to turn things around, however, with the release of Muramasa Rebirth for the Vita.
The game was presumed to be Japan-only, but Aksys Games has stepped up as a publisher and promised a full "relocalization" of the title for Western audiences. As with the original Wii release, only the game's text will be translated into English, leaving the game's Japanese voice acting intact. There's no news on when the localized version will hit shelves (digital and otherwise) or in which regions. Amazon does have the game listed for release on June 25th, but that date is unconfirmed.
As well as high-res graphics and enhanced controls, Muramasa Rebirth is also getting a glut of DLC in the form of four additional scenarios and characters. There's no word on how much these DLC packs will cost.
