Maybe I've misunderstood something, but these are the advantages of HDMI (real or promised):

1. One cable for video and audio.
2. One cable for multi-channel audio (DVD-A and SACD)
3. 12-bit digital video (DVI supports 8-bit)

So, for my tastes, the HDMI is the obvious choice. Not only does it reduce the tangle of wires needed, but it does everything better than our current connections.

On the audio-side, we can keep multi-channel audio in the digital domain and then allow the pre-pro to do bass management and time correction. No more digital-to-analog and analog-back-to-digital nonsense over 6 cables.

On the video-side, we can pass up to 12-bits of info (vice 8-bits in DVI), which can go a long way towards smoothing out the picture. Now, of course this requires the electronics in the TV to handle it as well, but the potential is there.

In theory, some day we will get a universal transport which just pipes digits over a single hdmi to our pre/pro and TV. We won't have to pay for all of the software and redundant electronics of our current DVD players. I could live with that!!!!
