I'm not exactly sure how this is going to work. Some manufacturers will be bundling cards with their boards. I've seen a few with different connectors. Some of them have 6 analog audio outs, others have just the S/PDIF (which would be fine for alot of people), some with Ether, others no.
I guess we'll know when the boards hit. Personally I'd like one with just the SPDIF and Ether, and that would be fine for me.
