Cryoakira,
Krieger is a nice demonstration, but nothing really new, similar methods have been applied to games and demos for decades whenever this made sense, there are many current and past examples. More space is needed for the long run. High quality textures and audio take up a lot of space, developers will re-use much of the already implemented technology in future sequels for new franchises, creating more audio-visual diversity (for example more levels) with higher quality for such games will require dual layer Blu-Ray discs.
On average the PS3's Blu-Ray disc loads faster than a XBox 360 can read a dual layer DVD (12x slows down to 8x, max speed only possible for the outer tracks). The XBox 360's current HD DVD drive is a single speed drive, probably about half the speed of the PS3's drive (the minimal bitrate for all BR players is higher than for HD DVD) I really have to wonder why this misinformation continues to exist, just like much other stuff I read on the internet.
