No, sadly it’s not a cruel April Fool’s joke…Sony’s Japan Studio, responsible for everything from Ape Escape, to Shadow of the Colossus, to Gravity Rush, is shutting down today:
"In an effort to further strengthen business operations, SIE can confirm PlayStation Studios Japan Studio will be re-organized into a new organization on April 1. Japan Studio will be re-centered to Team Asobi, the creative team behind Astro's Playroom, allowing the team to focus on a single vision and build on the popularity of Astro's Playroom"
