Apple Newsroom, with some new content information for Vision Pro (finally):

With Apple Vision Pro, users can experience Apple Immersive Video, a remarkable new entertainment format pioneered by Apple. Apple Immersive Video features 180-degree 3D 8K recordings captured with Spatial Audio to transport viewers to the center of a place, moment, or story. At launch, users can enjoy a curated selection of immersive films and series on the Apple TV app at no additional cost.

That link has details about the debut titles:

• Alicia Keys: Rehearsal Room
• Adventure — adventure athletes in exotic locations
• Wild Life
• Prehistoric Planet Immersive — “Viewers will transport into the daily lives of dinosaurs, experiencing T-Rex teens crashing a quiet colony of pterosaurs on the beach until mama shows up to break up their party, and an intense battle between raptors and a pride of Triceratops in the forest.”

There’s only a handful of these new immersive experiences, but the main thrust of the Newsroom announcement is to emphasize that Vision Pro is a killer device for watching any movies or TV shows.
