The latest (leaked) issue of Famitsu brings word of a new project from Vanillaware, creators of Muramasa: The Demon Blade and Odin Sphere. Vanillaware's Grand Knights History is a new RPG for PSP to be published by Marvelous -- with whom the dev worked with on Muramasa -- and planned for release this summer.

Players control the leader of one of three warring factions -- "Logress, the ancient kingdom," "Union, kingdom of the knights," or "Avalon, kingdom of magic," -- and take part in turn-based battles accompanied by a group of knights. Grand Knights History is said to include some kind of innovative online play that Vanillaware has yet to explain, but it involves connecting with other players during battle -- and allows for "infinity" players.

Chances are we'll hear more about the online system soon, as the game is reportedly 70 percent complete. And knowing Vanillaware's previous output, we can't wait to see the first screens.
