Half the appeal of the Onechanbara hack-'n'-slash games on PS2 was the price. With that gone, all you've got is the other half – the one with the boobs.
Onechanbara: Bikini Zombie Slayers for the Wii retails for $29.99 while Onechanbara: Bikini Samurai Squad will set you back $39.99. The Wii game is supposedly a sequel to the 360 game – although I doubt that matters since the "plot" in these games is a secondary concern. All you need to know is ladies wear bikinis, sport swords and kill a lot of zombies.
