The quote was:
"Lair takes advantage of all of the aspects of the PS3: 1080p graphics, 7.1 uncompressed surround sound, an epic musical score, motion control on the SIXAXIS [controller] and enough content to fill 25 gigs, all in the service of telling this fantastic story. This is a game and experience that literally could not have been done on any other system, past or present, and that is just amazing. "
That's not like saying they pushed the PS3 to the max, just that they made use of some key benefits the PS3 provides.
