While I agree that Blue-ray is the superior format, I’m hoping it doesn’t succeed. In all honesty, I hope both the current offerings fail – I’m really hanging out for holographic media.

A Holographic Versatile Disc (HVD) can hold upto 3.9TB (yes, Terabytes!) with a transfer speed of 1Gb/s. But I’m more interested in the card variant - HVC:

I agree with marc about solid state media. Whenever there are moving parts, it’s only a matter of time before the device fails (fatigue due to mechanical stress) – I hope future efforts focus on solid state design.
Sorry to drag this further off-topic, but has anyone heard any news about these? According to wiki the HVC is due for a Japanese launch some time this year, with the cards costing roughly $1.00 
. Though the reader will be about $2000
