To bee frank, sound outputs haven't changed all that much the last few years. Coaxial and Fiber have been around for a while, and firewire has become another standard (this time for DVD-A). Can we expect to see a coaxial/optical/firewire audio outputs on next generation. Also interesting to me is what kind of audio codec will we see. Will we switch over to DTS, remain with Dolby or what? 5.1 doesn't seem out of the question to me, 6.1 is pushing it, but come on, did I spend that money for a few rare dvds? What do you guys think?
