Just today, Warner Bros, producer of the Harry Potter films, released a new hi-res still taken from the seventh or eighth films, displayed on the left.
At a glance, the background looks similar to the
land surrounding the Weasley's house,
the house where Harry's friend, Ron, lives.
If this guess is correct, then this scene would be included in Part 1of the two films, as Harry doesn't return to the Weasley's house again
after this point.
Second is a production photo (below) showing filmmakers hard at work on a scene at the home of Harry's school rival,
Draco Malfoy, played by Tom Felton,
and his father, Lucious Malfoy, played by
Jason Issacs.
