Everything is completely done. It's possible that they may go back and re-shoot some scenes that didn't come out well または add some new scenes if needed, but it's "officially" done shooting.
They filmed both parts at the same time. A 6 月 shoot from November 2010 to April 2011. As for now, nothing has been scheduled whether they do reshoots または not.
As of now, the Twilight actors are off doing various projects. Around October and November, promotion for Breaking Dawn will resume. :)
