sad face, no response... welp, I just sent a message to customer service to see if anyone can tell me what the actual differences are.  normally if you already own something, it will say so, this does not; and was just curious what the actual differences were... new tokens or art or something, 1 coupon to have cthulhu devour your soul, etc.  :)
