About the the death of the winning Blue Ray Disc

In my point of view, the Blue Ray Disc is actually dead. The movies in Germany are still too expensive.

NEC, Microsoft, Toshiba, Intel, IBM und Hewlett Packard had formed the HD-consortium to promote the HD standard.

The all deceisive question however is: Why should one buy a mechanical disc with a movie or software on it when all stuff could actually better be stored on a USB-stick ? Since the 8 GB sticks are out and other non-mechanical memory devices surely on their way, why should one use an antique mechanical disc system ?

The only reason seems to be for copy protection purposes. I wonder if that is a sufficient reason to become a successful product ?

Maybe a small company who builds a copy protection into a USB stick will be the final winner ? If I were in electronics, I'd bet on that.
