on this week's Magazine, there were 4 color pages talking about the movie, and it confirms the story line from the movie website.
Spoiler for movie:
which says the secret of pactio will be revealed, as expected from that, the movie will be dealing with Negi picking a permanent partner/pactio before graduation, (to tell the truth, I have no interest in that, I would rather know how Nagi temp pactio with Rakan.
) in any case, the Negi is a prince coming to Mahora looking for a bride tale is going to be told for the movie
my own guess? the clue so far is Asuna is the only one shown in her MW clothes in the movie preview, all the others are in their school uniforms...
