I literally got my first one 2 days ago out of the gorgon chest. I'm glad everyone gets to have it, but it is kind of frustrating that I went on a kind of exotic quest, running crota on all my characters, atheon on all my charaters, 3 nightfalls and pretty much evert hinges that has a chance of dropping an exotic, and when I finally got it, he sells it 2 days later. Grrr xur lol.
