Naughty Dog's 'The Last of Us' Delayed

The Last of Us has had its original May 7 2013 launch delayed to a worldwide Jun 14 2013 release.
Developers Naughty Dog released a statement last night on the PlayStation blog:
As a team we pride ourselves on setting a very high quality bar for every aspect of our games – gameplay, story, art, design, technology and more. We want to make sure The Last of Us raises that bar even further – for ourselves, and most importantly, for you, our fans.
According to IGN, Naughty Dog has never delayed a game after publicly stating a release date, so we wonder what could have cropped up. The new release date has yet to be reflected by local gaming stores at time of press, so take note when placing your order.
