I am in the same frame of mind as CV. I stream more content than I buy/watch on Blu Ray, however anything I know I will watch numerous times I buy only on Blu Ray.

I think people feel the convenience of streaming movies, just like downloading music, far outweighs the need/desire to have the higher definition hard copy on hand at any time. I also think most people will only watch a movie once so do not feel the need to purchase movies unlike music which they will listen to over and over.

Anyone checked to see if over all movie sales has dropped off over the last few years?

I am waiting for movies to be offered as downloadable for sale content just as music is, I only hope the HD versions are available.
