Not sure if we all saw the same video (below), but without a doubt the most disheartening comments were around the line of DSD is good, but Double DSD, man, that sounds like vinyl/studio/real/whatever...
That said as long as the hardware is compatible it's more a 24/96 v. 24/192 than BR v. HDDVD comparison (at least in playback competition), no? And of course the number of DSD studio recordings (before PCM mixdown to Redbook, etc.) has to be huge compared to the number of SACDs ever released or current DSD downloads.
Again, I'm excited about DSD, but the difference between DACs at the before mentioned DAC-off was greater in any format than between formats. Thus buying that good old ECD-1.
