A new promotion from Red Bull may have accidentally let slip the name of the next expansion in the works for Destiny. The promo shows off a means to get "bonus XP" for something called Destiny: The Taken King. It also makes mention of a Flamesword, which could potentially be a new weapon or game mechanic for the expansion.

The images originally came from Agrios Endendros via Twitter (2).

The expansion is still probably quite a ways off, however. The newest expansion, House of Wolves, was only released a couple of weeks ago now.
