Doc - These days, many journals (except a few NEJM level journals) publish articles online (accessible via PubMed) as soon as the article has been accepted and copyedited (a process of a few weeks after acceptance in my experience). So, in these circumstances, there is no waiting for publication - it happens online as soon as the article is available, and then comes out in printed form later. I have never heard of authors trying to schedule a specific publication date with a journal, and suspect that would be quite hard due to the mechanics of publishing paper copies of a journal (there is usually a backlog of accepted articles waiting for publication). Doesn't mean it can't happen, but I have never heard of it. Journals like NEJM routinely schedule publication dates (not in response to the authors' wishes though), because they need to arrange all the PR that goes out with their top articles.
