I really doubt itd be any closer. Your whole argument falls apart when we consider Disney, a multi multi multi billion dollar a year company, has had the release date scheduled for months before releasing it. This said company, being films is one of the greatest revenues for them, would be fully aware that the calendar would negatively impact sales. This company would also be aware that any other company would want to avoid facing the juggernaut of SW in the box office directly. Disney would be able to announce what date they would want and keep it and force the other companies with much smaller movies to release that week later.
