Yahoo! released the first behind-the-scenes look at Ron and Hermione's kiss from DH 2, including a proper shot of their snog. That will be featured as part of the eight-part HP DVD/BD collection.
A bunch of new on-set photos from DH2, including of Voldemort in the final battle, the trio in Gringotts, and more, were featured in the trailer for the upcoming Harry Potter Page to Screen book. That can be seen here.
