Well weather anybody cares about it or not my 7.1 Energy, Pioneer, LG 50" plasma set up is perfect for experiencing the games being developed today especially the ones coming from "Sony's first party" developing houses :) they are totally taking advantage of the Blu/Cell capabilities of the PS3.
I'm sorry you are only playing HALF the game with a 2 channel setup, sad but a very true statement this generation.
Sometimes I even wonder if the web/magazine critics even play (review) taking full avantage of games, I have never read anyone talk about the "localize" sound option on games like Socom, its insane, it totally brings a new level to the game.
I just think that it should be advertised for us in the back of games, "7.1 Lossless Audio!!" ;)
