Today at Sony’s E3 keynote,  they have  released the first gameplay demo for The Last Guardian since 2009 , unfortunately we didn’t get a release date but it is due in 2016 , But for now, a new gameplay demo to show the game is still being worked on, is more then enough.  The Last Guardian was originally supposed to launch in 2010.
