Following what Paradox said in this topic:
They updated the topic today, I think just because people wondered your question, but I agree that this is a little ambiguous.
I've just noticed that on http://www.europauniversalis4.com/buy now they have two different sections for the pre-ordering of the digital extreme edition and the standard one; does it mean that July and August bonuses could be different for the two version pre-order??
Admittedly, I wish the Extreme Edition had more DLC to it, simply because it charges more and the DLC with it aren't the very best.
Paradox, you offer incentives for sharing this game with my friends, but I don't have any friends, because I'm always playing your games!
I have friends, but only because they don't know that I play these games. I'm very sad that I can't get at least three recruits.
