Kenji Kaido and Sony have parted ways, but it's unclear if the ICO producer was working on The Last Guardian.

Kenji Kaido, producer of both ICO and Shadow of the Colossus, announced today that he has resigned from Sony Computer Entertainment. It's unclear if Kaido was working on the The Last Guardian, if so this will be yet another setback in the game's already troubled development.

Yoshifusa Hayama was serving as executive producer on the project before he left to join Facebook game developer, Bossa Studios, in December of last year. The game's director, Fumito Ueda, also left the company, but he's still working on the title as a contractor.

After failing to show The Last Guardian at a number of trade shows, Sony admitted that its Tokyo Studio was having "technical difficulties," and announced it was bringing in Sony Santa Monica and other western developers to assist with the oft-delayed title. Since then, we've heard very little about the game.

After leaving Taito in 1997, Kaido joined Sony, where he worked on Tomba! and served as lead designer and associate producer on Ape Escape. His last game for Sony was apparently 2005's Shadow of the Colossus.

According to GameLife's translation of Kaido's twitter announcement, he hasn't decided where he'll work next. Instead, he's going to continue his summer vacation.
