Shuhei Yoshida, president of Sony Worldwide Studios, has said development of Team ICO's The Last Guardian is progressing, but very slowly.
Speaking to 1UP, the Sony exec attributed the sluggish pace of development to challenges in realising Fumito Ueda's vision.
"The project has been making progress, but slow progress. So that's tough, but we haven't changed any focus. It's still a really important project and a vision we want to see realised, and Fumito's vision is really causing a very difficult challenge for the developers, so there's some scrapping and rebuilding - iteration in the process. That's why [it's taking so long]," he said.
Late last year Ueda, who served as leader of and director of The Last Guardian, left Sony. However, Sony moved to calm fears surrounding the future of the project by stating that Ueda was still 'committed to completing' work on The Last Guardian.
Yoshida took the opportunity to once again ensure fans that Ueda is still closely involved with the project.
"You know, we discussed an arrangement so he could focus on the creative side. But his work and his presence on that team never changed, so it was just more a contractual rearrangement, and that was taken [by many] as 'he left', said Yoshida.
"He comes in every day, and he's probably one of the people who works the longest hours."
Following Ueda's exit US retailers mistakenly informed pre-order customers The Last Guardian had been cancelled.
