Next year there is a new format of disc coming out called a "TERRA-BITE" disc that will be able to hold about 25 movies on 1 disc
I remember reading a few years back that we would have 3D discs around 2010 - so maybe it's the same thing with a different name, as that could hold around the same amount of stuff.
That is why I haven't bothered with Blu-Ray.
I've been saying for a few years that the disc format is going to be dead soon anyway - as technology improves we will be buying our movies on swipecards that will just be swiped down the side of our tv set.
Betcha I'm right.......
