No new dates have been given but The Last Guardian was supposedly going to hit toward the end of this year, so we can only assume that there'll be no sight of it until 2012.
Over on the EU Playstation blog, Ueda has issued an apology:
"I announced at last year's Tokyo Game Show that the release timing of The Last Guardian which is currently being developed would be holiday 2011.In fairness, if the delay means the finished product will be all the better for it then we can't really complain. The Last Guardian is already shaping up to be a beautiful looking game and once we have more information it'll be here so stick around.
However, to provide more challenging and better quality of content to users and to fulfill First Party Studio's obligations, I decided to postpone its release timing.
All the members of my production team are working together at a fast pace to develop and release the game in First Party Studio quality.
I sincerely apologize to all the customers who have been waiting for "The Last Guardian" for so long, but I beg for your patience. I will also announce the new release timing at a later time.
