Just stumbled across an announcement from a few days back that Sony is pushing a new CD standard called "Blu-spec CD". The articles I've found on this seem a little confused with many suggesting it's a new format, but as far as I can tell they're simply manufacturing Redbook compliant CDs to higher tolerances.

Here's some of the more informative links I found.

sounds like marketing to me... i guess your 1's and 0's will sound better? lol

additionally im so tired of reading everyone talking about blu-ray and "blue" lasers... BR uses violet lasers

Blue lightsabers had 2x the sonic potential of red lightsabers. True story.
