The Last Guardian does exist and development continues on the project, an anonymous Japanese developer for Sony told Kotaku at the Tokyo Game Show.
"I give you my word that it exists," said the developer. "We are working on it."
The developer's comments come amidst growing concern that the PS3 game may never see the light of day.
The developer added the game is a "very ambitious project", and suggested it was announced too early. The dev also explained that "there are lots of pieces of the puzzle," and that "it's a matter of getting them to fit together".
We still reckon The Last Guardian may end up on Sony's next console or, much like Shadow of the Colossus on PS2, may be one of the last great PS3 titles.
