Previously referred to as Project Trico, the next title out of Shadow of the Colossus and Ico developer Team Ico has been officially announced as "The Last Guardian."

Coming to PlayStation 3, Guardian is the third entry in the Ico trilogy, according to Sony CEO Jack Tretton. A trailer was shown, with many scenes from the leaked video sporting added graphical detail, along with footage of the boy sneaking around enemy soldiers and, later on, throwing barrels at another batch of soldiers.

Unfortunately, the PlayStation 3-exclusive story of a boy and his colossal feathery companion does not yet have a release date.

What is likely an early bit of footage from Team Ico's next project--a work apparently known as "Project Trico"--has leaked by way of PlaystationLifestyle.net.

The video shows a game that blends the companion-based gameplay of Ico with a massive rat-like creature reminiscent of Shadow of the Colossus. This combination has previously been hinted at by Team Ico leader Fumito Ueda.

"[Team Ico's new project] might be something similar to what's been done," said Ueda at this year's GDC. "Kind of a middleground... the essence of the game is rather close to Ico."
