I can't 'post an answer' to the question below, so here is what I have heard. The movie will be around an hour long, and is slated for a July release in Japan. There is no firm date for a UK or US release, but as Square are making a big thing out of it (and their presence abroad), it is likely to be soon after. I guess the main factor is whether they dub/sub and release it themselves, or whether they sell it to a distributor who will then have to dub/sub it. The former option seems more likely. The film is going straight to DVD at the moment, and given the poor performance of the last FF movie, this seems unlikely to change.
