Streaming services will slowly get better. BluRay probably won't.
Compression techniques on blu ray have already gotten much better since the initial releases on blu ray. That much is evident in the picture quality. Avatar on blu ray was unlike anything that I have ever seen in my entire life in terms of image and sound quality.
I’m not interested in dvds or streams. If a movie is good and should be watched, then it should be watched on blu ray in my opinion.
