The Movie opens in Japan next week, but they had a premiere screening during the week for the media, with guests on hand (director, producer, Japanese voice actors and the main girl on screen).
I thought it would actually increase piracy, as those people who were more likely to buy a physical copy (for them, or more importantly, their kids), would now go find a digital copy if they can't wait the extra two weeks, and prefer not to pay for that digital copy if they intend to get a physical copy. And then later maybe decide not to buy the physical copy now that they have a (free) digital copy.
