Nonsense OP, they will be releasing all the movie information you could hope for around about the 14th either on that kiddie pokemon show or in Corocoro.
That said, the information won't include things we actually want to know like sylveon's type but mundane crap about the film like who Ash's new best friend of the day is in the film with lots of meaningless phrases written at jaunty angles across the page in garish colours to disguise the fat they're trying to make a multipage artical based on one new fact about the film that nintendo have judged fit to give them.
