From what I had said above, I would conclude that
ultimately an HD-DVD format is *mandatory*. You can
only go so far with de-interlacing DVDs and
upconverting them for 720 or 1080 line HD displays.

The question of how best to upgrade is orthogonal.
Should stores be required to double-stock their items,
or should HD-DVDs also work in DVD players?

Last I heard, DVD-As are supposed to be playable also
on regular CD players, for exactly this reason. I
don't know if this has actually happened, but that
was the plan.

It's another matter whether DVD-A or SACD will succeed.
I don't know that the improvement is obvious enough to
the masses. And this is because CD playback has been
improved quite a lot just by tweaking the players,
without having to change the standard itself. That's
always the preferable route, as long as it's viable.
From an engineering perspective, that is.
