Fumito Ueda, the creator of Ico and Shadow of the Colossus, has apologised in an Edge interview for the ongoing delays which have affected The Last Guardian since its announcement in 2009.
Admitting that his personal creative work on the project was finished "a long time ago" Ueda said hat he was "terribly sorry for that for various reasons I have kept my audience waiting for such a long time".
Ueda departed from Sony in December, 2011 and now acts on a commission basis on the project.
"The details of when, where and how it will be completed are beyond my control. The original staff members on Ico and SOTC are just as fussy over details as I am. I always want to create quickly, and I always want to increase the rate of production."
Discussing his decision to leave he said:
"It was not easy. I can't go into the details just yet. It will be good to be able to discuss it along with a post-mortem of The Last Guardian someday".
Recently, Sony Japan Studios head Allan Becker commented that the game was "moving in the right direction". Becker also said that he and Ueda sometimes disagree on what route development should take.
While The Last Guardian was announced as a PS3 game it's likely now being developed for PS4 but this has yet to be officially confirmed.
