File this away in the "do we really need this in our homes" category.
Around here, we love surround sound just as much as the next guy. Current standards provide up to 8 separate channels for audio but Dolby Labs have used a little help from Intel's new VIIV and Pro Logic IIx to up-sample those channels to 14.1. Sure, while it is not encoded in those channels natively, testers did claim to hear a difference.
Dolby does not have any intentions on producing this anytime soon. Simply because none of the optical formats support this kind of signal.
Does anyone really see a need for this? Or a better question is, does anyone have the space for 13 speakers plus a subwoofer?
