A long time ago I read an article about the disc format it's going to use, back then they were called "Blue Discs", they look like encased CDs, big mini discs and are, hence the name, blue. Supposedly they have very small loading time and large, large storage capacity, more than that of a DVD I think.
The technology is called Blu-Ray, actually. It's been in development for years, but I think they're just releasing it publicly soon. Like 25gb of storage compared to the 4.7 of today's DVDs.
