I reckon that there won't be one particular leading storage format, but a range. I remember reading that article about SanDisk releasing music on memory sticks? I think that there will be several different way of obtaining media like videos and music and such, like Internets, maybe download access points (like a photo printer in a shop but where you can buy songs and put them on your music player without having to go home). I think USB media is gonna get bigger and stuff. I don't think DVDs are going to die out because to be honest they do have good quality still. Even VHS has good quality.
