Update 10/9/17: We’ve got some updated information, courtesy of Rhino Records. The set is actually only for the first five films.
Each soundtrack is contained in a gatefold sleeve that is die-cut on both sides (seen above). The images used for the picture discs are stills taken from the related films. The one exception is Harry Potter and the Order Of The Phoenix, which also features an etching on the last side of the LP. The set also includes a download card so the music can be downloaded.
According to listings at SoundStageDirect and Fat Beats, the Harry Potter soundtracks are getting released in a 10xLP, picture disc box-set. They haven’t released information or pressing details at this time.
Composers John Williams, Patrick Doyle, Nicholas Hooper, and Alexandre Desplat contributed to the series.
It’s scheduled for November 17th, so expect information soon.
