Sony has moved to explain The Last Guardian's no-show at E3 this week.
"The team is back in Tokyo is working hard, and there are some technical difficulties that the team is focused on right now," Sony Worldwide Studios president Shuhei Yoshida told Eurogamer. "That's why we don't have an update."
The exec went on to dismiss rumours that the game will now release on PS4 rather than Sony's current generation console.
"What does that question mean [is it still a PS3 game]? It is a PS3 game," he said.
Pressed on whether it'll ever see the light of day on PS3, he added: "When we have confidence in saying that, we will talk about it. But today, we are working through some engineering effort."
Back in February, Yoshida admitted that Sony has drafted in a number of Western developers to support SCE Japan Studio's Team Ico on the highly-anticipated and long-in-the-making title.
"It's not just [God of War studio] Santa Monica," he said. "We have great tech people in Worldwide Studios. We have a central tech group in the US and the UK so we are giving them whatever help they need. Technically, we have the best engineers in the US and Europe, so these teams are helping them, giving advice."
