A new title by Platinum Games for IoS is in the works. It is looking to be a game using the Okami art-style (easy for mobile) paired with a Shinobi styled combat system (even using the same helmet designers as in Kunoichi). No information yet on anything else. Still, it is interesting to see P* take on so many little projects, probably to fund the larger more passionate ones.
Let's just hope they don't get stuck in it.
