I'm not going to address the implication that somehow interactivity denegrates the audiophile potential of BluRay. As for video with audiophile sound, personally I'd love lots of opera on BluRay (when my ship comes in and I get an HDTV and a player).

But I'd wager plenty that 85% of consumers will remain blissfully unaware of BR's audiophile capabilities as they are of SACD and DVD-A as media. Nor will people be woed into the audiophile realm by the accompanying video: they won't hear the difference and of the few that will, most won't care. (Wooch himself mentioned the music lovers with nothing better than compact systems.) Audiophile are an eccentric breed. BR audio will always be a niche market for this small minority, at best.

At the risk of sounding like a broken record, I remind everyone that perhaps a majority of hardcore audiophiles are vinylphiles, (for largely irrational reason). BR won't sound like vinyl so these nutbags won't redirect their allegiance or budget to BR. The technical virtues of BR are almost as irrelevant to audiophiles as the the general population.
