I don't think DVD in general is going to fade away anymore than CD's have.

A lot of tv shows produced in standard definition are not going to benefit from a Blu Ray release. "Back catalog" releases, even of mega popular movie titles simply aren't going to get a simultaneous DVD release anymore.

More studios are mining their vaults for Made On Demand titles now, which may eventually benefit all those obscure movies we love that haven't seen the light of day since VHS ruled the land.

Pulling old store stock off the shelves seems like a calculated move to drive demand though.
