A screenshot from near the end of the O Brave New World ViDoc, featuring what many are now presuming is imagery from Bungie's next intellectual property, and is referred to internally either as "Destiny" or "Tiger"-- it's possible that both words refer to the same project or different parts of the same project, or different projects. The emptiness of the landscape, as well as other shots that seem to show authoring tools, could perhaps indicate a Forge-like function, either as part of gameplay or alongside it.

Take a look at Rampancy's gallery of screenshots from the ViDoc that showcase possible information about Destiny.
