In a recent interview from Siliconera with the head of Marvelous Entertainment they mentioned that the Parallax heavy game Muramasa : The Demon Blade might benefit from the 3D effect. Tomio Kanazawa responded favorably saying “That’s a pretty good idea! That is one of the many things we think our fans want, and we want to provide to them,”.
Marvelous has been confirmed to be working on several 3DS projects. One of which is a new Harvest Moon game and the other is Animal Resort.
There is also rumor going around that Muramasa may be ported to HD consoles such as the PS3 and Xbox 360 as a downloadable product.
