In early May, Bungie registered a trademark for something called "The Taken King." At the time, we posited that it could be something related to Destiny, or might be related to another Activision game (based on previous trickery).
An photograph has surfaced that seems to indicate that this is, indeed, the name of an upcoming Destiny expansion. The photo below is an image of a case of Red Bull. It bears The Taken King logo in the color (oxblood) specified in the trademark filing.
Additionally, another image has appeared online showing another angle of the box. As you can see below, it references Red Bull-sponsored pro gamer Michael "Flamesword" Chaves and includes his likeness.
We've reached out to Activision for comment. We'll update should we receive a response.
These box shots seem quite convincing, down to Flamesword's likeness. Of course, the possibility exists that these could be fakes. If not though, I suspect Activision is going to have some stern words for Red Bull.
