This is what I've been saying since day one...
Since the first day I saw/heard about Blu-Ray, super high resolution audio discs were one of the first things to pop into my head. I just hope Blu-Ray audio markets itself better than SACD/DVD-A and goes another step further to be a truly fully emersive entertainment experience, coupled with visual representations of the music and/or title and track information with notes from the artists/producers.
The music industry has a real opportunity to reach a whole new group of people (the average movie watcher) with high end audio. Maybe even more importantly, especially if you're an Audioholics reader, it means the eminent creation of higher end players from the likes of McIntosh, Meridian, Classe, and the other esoteric brands.
