I do hope 7.2 ends with a satisfactory wand to wand show down between Harry and Voldemort.
Somewhat a spoiler:
The book ends with an extremely unsatisfactory wand to wand confrontation between Harry and Voldemort. Personally I have some level of hope that this will be rectified in the film so that the contest is decided through actual skill and not flimsy coincidence (the trailers make it appear so), but who knows . . .
