From Tiger to Destiny by way of Demonware

Click in the image for the big picture. 

It's being hailed as a massive leak but it's not really. It's a post from some dude who works for a firm called Demonware who got to attended Bungie Day and hear all about the new Destiny game.

There's no real specifics here, everything is mentioned in a broad, passing sense.

Still, Bungie will be pissed this kind of thing was disclose, probably in breach of an NDA.
