Nope. Bungie can't put anything from Halo into Destiny because they gave up all the rights to Halo when they became independent in 2007. Don't believe me? Remember [url=http://en.wikipedia.org/wiki/Myth_(series)][b]Myth?[/b][/url] Bungie used to own that but when they joined forces with Microsoft, they abounded all rights to Myth. Have you seen any Myth Easter eggs in Halo? Nope. The same will be for Destiny and Halo. There maybe subtle hints but nothing from Halo will be in Destiny.
