A senior PlayStation executive has apologised for the continued delays to Sony's long-awaited The Last Guardian.
Hopes for new information on the project were higher than usual during the build-up to Sony's PS4 announcement. Last week, the game's principal developer updated his personal blog and said "keep an eye out" for any announcements.
But the PlayStation 4 event featured no information on The Last Guardian.
The persistent lack of new information has led Shuhei Yoshida, the head of Sony's game studio division, to address fans of the project.
"I apologise to people who are waiting for the game," Yoshida told Kotkau.
"Ueda-san posted that he's still working on it, that he's creative-directing it and that the team in the Japan studios are working hard," he added.
"We are waiting for the right time to re-introduce The Last Guardian."
It is expected that The Last Guardian is now a PS4 project, though Sony has never confirmed this. Switching development between both systems would explain the extensive delay, but this is only a suspicion in some industry circles.
Asked whether the Last Guardian would appear on PS4, Yoshida responded "we're going to talk about it when we can".
Sony revealed the PlayStation 4 at a New York press conference on Wednesday.
The PS4 release date is set for "holiday 2013", likely across Japan, Europe and the US.
