so far I've played cod 3 and resistance and all I can say is zero lag, and using a bluetooth headset, voices are WAY clear, just liek using your bluetooth on ur celly. My freind has the other consoe and voice on ps3 is WAY more clear, which I was VERY impressed with that alone.
voice chat is missing features, and why do i have to call my friend to get him to load up resistance before i can invite him? He's on the XMB, why can i send an invite? And why doesn't the ps3 have a similar background system to the 360 in games? To see who's on their PS3, I have to quit to go back to the XMB?
