I've gotten 3 exotic drops so far. The Ace of Spades, which I already had. The Telesto, which was literally in my inventory at the time. The Darci, which I already had. Friend who just got destiny had the 2 tailed fox drop, even though he has yet to obtain 99% of the exotics. Seems like the Foresaken exotics will drop at a higher rate if you just obtained the game and haven't collected all the other exotics.
