@digital_idiot: so my girlfriend was playing SI:IG today and we had the surround sound muted. we heard a faint, short hiss from the speakers, the same sound my system makes when changing sources or going from stereo to surround. so i changed the source from the xbox to just the tv output, and it was just fine. the sound didn't drop once. i'm thinking it has something to do with the dolby digital output. hope that helps a little.
@bearshamanbro: speaking as a casual fighting fan, it felt good. from what i heard around there, it's the same engine as TvC, just prettier. really, i only got one game in, but it controlled the way i thought it should have. i really want to get my hands on it again.
