I remember back in the the PS2 years Xbox always advertise their sound capabilities in their boxes, I was so pissed that lots of my PS2 games lacked 5.1 surround sound :( I remember buying games just because I wanted to experience them fully with my home theater, Terminator 3 had DTS!!! nowadays lots of PS3 games feature full blown lossless 7.1 sound yet by looking @ the box info you wouldn't know, bluray is what makes that possible they always want us to know that, I think that aspect of the PS3 is as impressive as its graphic capability.
