Platinum Games was created in large part by former Capcom-employees, with Shigenori Nishikawa at the helm. He's previously worked on games like Dino Crisis 2 (and 3) and Resident Evil 4, and the last time we saw anything from him he was the director for Platinum's hard-boiled Wii action game Mad World.
Now Platinum has revealed that Nishikawa has left the studio and gone to Resident Evil-daddy Shinki Mikami's newly started studio Tango instead. It will be very interesting to see what those two men can come up with together.
