If I had to take a hunch based on Vanillaware's past titles, it's safe to say it's going to be an action role-playing game in a vein to Muramasa: The Demon Blade and Dragon's Crown. My main question though is how the Sentinels are going to be handled from a gameplay standpoint. Something along the lines of the King of the Monsters or Rampage games maybe? Maybe Super Robot Wars? I don't know.
