It'll come in a couple of days. No worries! I did not order my first iPad till about a month or so after launch. It still had the excitement of iPad land since I had to specifically sign up for one at the Apple store and wait for the pick up email, etc.
That's still a fantastic time to ship. It was much worse to try to get an iPad 1 or an iPad 2 if you missed the launch window. Months. Having it delivered just a couple of weeks away is a very fast turnaround for this demand. They must be seriously pumping out the product.
