I know a lot of people think that the disk system should be done away with, but those are probably people in quasi-urban areas with decent internet connections. I have a feeling that there is still enough demand for hard copies of things that this next Xbox is going to have some kind of disc system...

So how about this bad boy? http://en.wikipedia.org/wiki/Holographic_Versatile_Disc I wouldn't mind a disc drive if the discs have a theoretical maximum size of 6 TB.
