Noob question:
2. PS3 games audio in 5.1/7.1 surround sound?
I might buy a PS3 slim next year, plan to use a 22"/24" HDCP support LCD monitor at resolution 1920x1080 via HDMI for display; and might get a cheap HTIB for audio. But if the games are not utilizing surround sound maybe I'll just get some 2.1 speaker.
3rd party games are
MOSTLY in 5.1(Mirror's Edge, Ghostbusters,MGS4,etc)*
only some 3rd party games are in 7.1(Batman Arkham Asylum,GRID,etc)*
but
ALL first party games are in 7.1(Resistance 1,2,Killzone 2,Uncharted 2,etc)
you do not want to get a cheap HTiB,believe me..i know

go get a full fledged 7.1 HDMI system,and you'll be absolutely sucked in by the games.
unfortunately blu ray movies are generally 5.1 only

only some provide 7.1,and 6.1
*not all games have a perfect mix,though when it comes to 7.1 surround.
racing games have a near perfect mix, i think (tested GRID,GT5p,etc the sounds come out from the right speakers at the right time.)
action/adventure games however, may have issues.
despite being in 7.1, the sound occasionally come out from the wrong speakers...(tested Uncharted 1,Batman Arkham Asylum)
example: Batman AA; i blow a wall that is in front of the character, yet the rear speakers emit the explosive sound made in front
