Premise: Posted Today, 05:04 AM Note that it's not all Gold editions dropped to $39.99. It's that if the Gold ed of a game has been "merged into" the standard edition (see that other post for discussion of titles), the Gold ed will ring up at whatever the standard ed is going for at Target. $39 in the case of ACO.
Hypothesis: Gold editions of the game will no longer ring up as gold editions.
