According to a large number of users on the Destiny subreddit, Best Buy is cancelling pre-orders for the Ghost Edition of the game. Specifically, the cancellations seem to be happening to PS4 pre-orders, as the demand was so high that they actually overbooked the total allotment. Xbox One users aren't reporting issues and can confirm their pre-orders are still being honored.
It's possible that scalpers learned of this early on, which is why they're currently going for two to three times their retail value online.
