Jason Isaacs completes Malfoy Manor filming

BBC Radio 5 interviewed Jason Isaacs recently and discussed Deathly Hallow filming. Isaacs confirmed that he has completed filming the Malfoy Manor scenes and will return next month to shoot some scenes with Voldemort--the Battle of Hogwarts possibly? He could not confirm the split point in Deathly Hallows, but you might recall that our MuggleNet sleuths uncovered that Josh Herdman revealed the split point to be before Malfoy Manor.
