Everything new is initially very expensive. However nothing prevents people from taking these movies and downscaling them for the Quest 3 lenses so you can watch it on a cheaper hardware. Current 8k 180 or 360 content for the Quest is really bad quality. While the Quest displays are lower quality (and I think the Snapdragon is also more limited than the Vision), downscaled content should still be far better than the movies we have right now.
