Not only is it typical, but it's what I reported a few months ago. I believe Hasbro actually was saying that their original date of "July" was being pushed back a little though, not their "September" date, here's their exact response: "They had to go back and rework them a little bit so they are behind schedule." This isn't news to me, it just sucks that they themselves put out all this information on sw.hasbro.com and sw.com about how these would be out on time in June/July when they already knew they wouldn't be.
