Bluray will gradually become more common. I think the biggest threat to its success now isn't dvd but streaming video. Having access to a movie whenever you want it (like on netflix for example, as annoying as netflix has become) makes owning the movie seem unnecessary for a lot of people. Something hollywood should think about when pricing blurays.
I still believe its unlikely we'll see the fox fanfare unless it's part of a deal to get the rights to the original trilogies earlier than 2020.
