Marvellous unveiled upcoming Vita title Oboro Muramasa during Sony’s TGS press conference, but didn’t give any details beyond a March 2013 Japanese release date. Follow-up reports suggest the game is an enhanced release of Wii classic Muramasa: The Demon Blade, with added bells and whistles. According to Gematsu‘s translation, the gorgeous slasher will be backed up by DLC, including an entirely new module called Mysterious Legend of the Genroku Era to be detailed in Famitsu this week.
