The Last Guardian is still in development, the game's ex-director Fumito Ueda has confirmed.

In an open letter published on his website, Ueda revealed that the title "remains under [his] creative supervision", but that details regarding its release are "solely decided by Sony".

"As some of you may have heard, I left Sony Computer Entertainment Japan Studio some time ago to pursue my creative passions," said Ueda. "Nevertheless, I continue working on THE LAST GUARDIAN as a freelance contributor."

"While it's been a long time coming, THE LAST GUARDIAN remains under my creative supervision and is still in development by an incredibly talented team.

"I should also mention that details regarding THE LAST GUARDIAN's release is solely decided by Sony Computer Entertainment, not myself. Please keep an eye out for their official announcement."

First announced in March 2009, The Last Guardian hasn't been seen since early 2011, with rumours suggesting that the game may have been moved to Sony's next-generation PlayStation.

Ueda continues: "Moving forward, it is my intent to continue my involvement with THE LAST GUARDIAN project, as well as pursue new creative projects with a fresh perspective.

"As I rekindle my passions as a creator, I look forward to seeing where it will take me, and I deeply appreciate your support during this transition."

Sony is expected to reveal PlayStation 4 next Wednesday, February 20. Could The Last Guardian be one of the surprises in store too...?
