"High Definition Audio

The High Definition Audio on the chips runs at a maximum of 192KHz 24-bit sample rate with eight channels, plus Dolby, DTS and DVD-Audio support. It also supports array microphones with up to 16 elements, a rather under-utilised technology that's useful for noise-cancelling voice recognition systems. This may be a feature of future operating systems. The final trick that the audio subsystem knows is 'jack retasking': it senses whether you've plugged a microphone, speaker or line-level audio connection into each jack and routes the audio signal appropriately. This could spell the end of the incomprehensible audio icon."

What does this mean for the end user? "The High Definition Audio on the chips runs at a maximum of 192KHz 24-bit sample rate" - does this mean there won't be any resampling?

Not necessarily, an audigy 2 still resamples 44.1khz to 48khz but supports 24/192. In order to fully support DVD-A the chip would have to be able to support 24/192 since the stereo DVD-A spec allows for it, and it is used on a small number of current DVD-A discs. Also, 24/192 DACs are pretty much standard these days.
