IIRC, Hasbro has said that the BMF will continue to ship through the holiday season. So we should not have a problem finding this between all of the big box stores. We might have a problem at first as I expect this to sell well early. But a month or so after release it should start popping up again.
It's just that "gotta have it now" tude that most of us have that makes us excitable about something like this.
Patience, soon you will have your Falcon.
