It is not clear what this means for the project.
Yoshida was asked about SCEA Jack Tretton's recent comment about the game being on "hiatus." He said describing development on the game this way is a little off-the-mark.
"Hiatus, I never… It was Jack Tretton! He used that term, and I said no, hiatus is misleading," Yoshida said. "It was a hiatus in terms of releasing new information. The game has never stopped--the team has always been here. They're going through the reengineering of the game, so the team size is smaller, because it's more engineering focused right now."
Asked what platform The Last Guardian would be released for, Yoshida said, "That I cannot talk about." The game was formally announced in June 2009 for the PlayStation 3.
"So, we're waiting for the right time to reintroduce The Last Guardian in an appropriate way. I can't… Well, the game is in development, and it's well staffed, and Ueda-san is here, working--even though he's not a Sony employee, he's dedicated to the product. But we're not ready to update yet."
The Last Guardian has made "slow progress" for years. Sony senior vice president of product development Scott Rohde said during E3 2012 that the game will ship "when it is absolutely ready." He also said Sony has no deadline whatsoever for the game.
