Just a quick question about the X360. I was looking at the pics on IGN.com from the GC in Germany and I did not see any digital sound outputs on the system. I think the HD cables that come with the system come with cables to enable digital sound (DD surround i guess) but is it via analog cables? Does X360 have optical or coaxial digital outputs for sound? (sorry if this is a stupid question but i figured I'd ask instead of searching the whole WWW). Thanks
