I have a sneaking suspicion that they're going to spread the goodies out over 2 weeks or a month so we all have time for our wallets to recover and buy ALL of it instead of having to choose one or two of the cool items along with the rulebook this week.
They managed to get the red dice in stock for the Gamer's Edition set so I don't think they're really having issues, they just want the hype(and sales) to last a little longer.
