Considering the storage capacity of that monster I'd hope they'd use a plastic casing similar to those used on Magneto Optical disks.
Everytime a new large format disc comes out I keep hoping and praying for this, but each time they keep releasing naked disks that are prone to scratching, smudging, dust, and increased wear and tear.
Especially when it comes to home video use. I'd love a next gen storage medium that used a hard plastic casing with a metal door over the read area. I'd feel much safer letting my nephews and nieces handle the things. Rather than having to put in all the movies for them as I do now with DVDs.
Hell if Blue-Ray or HD-DVD had used a protective shell for their disc's I'd have bought one in a heartbeat even with the limited selection of movies.
And yes, I realize it'd add a dollar or two onto the price and that they would take up more shelf space. However, it'd be soooo worth it to me for the peace of mind, knowing that they would be "relatively" difficult to trash compared to current DVD, Blue-Ray and HD-DVD. One of the reasons I still use MO disks for my family photo backups.
