http://shop.gameplay.co.uk/webstore/genre.asp?platform=XB360&parent=PERIPH&genre=PERI10 The above link shows the cables available for the 360 on release? None of these allow for 5.1 sound into your 5.1 system like an optical ouput. I am very worried as just got a new Pioneer 5.1 system which I cant see how I am going to get into my 360 now. The only spare port on my 5.1 system is the optical in (line 2) and on top of that my tv has no component so am going to need a scart lead. The advanced scart lead on the above site looks like the current one where the optical output is included in the lead which would be ideal.
