When blu-ray or HD superbit disks come out, buy Blu-ray. (yes, Sony pictures pushed the superbit format)
I can't imagine what the quality of a Superbit Blu-Ray disk would be. My old dvd player actually has a diagnostics mode where you can see the mb/sec of the stream being played, and the few superbit disks we have, are often running at double to triple comparable disks. There are really only a few scenes where the difference really is visible.
It is funny to watch some movies with that and you can see that they changed the compression ratio throughout the movie to maintain the best quality they could and still stay on one layer. Now of only they could engineer that layer switch to be less visible.
