ITs a new type of disc that holds more than a dvd! Its maximum capicity is 24 gigibytes and later increased to 36 gigabytes! The reason why its called blu ray is because the laser color is blue instead of red. This helps debunk the theory that the ps3 will draw data from the net. This info was reported by the dec issue of OPM. This is cool stuff! Imagine the stuff that can be done with that much data! Imagine the power of the new system! But, what about copying the games? Could this be a gamecube case?
