Not according to the FAQ:

1.10 Will Blu-ray Discs require a cartridge?

No, the Blu-ray Disc Association (BDA) and TDK have successfully
developed a new hard-coating technology dubbed "Durabis" that makes the
discs even more resistant to scratches and fingerprints than existing
DVDs, without requiring a cartridge to protect the discs. This
development will enable manufacturers to downsize PC drives and lower
their overall media production costs.

I think the dual-standard discs can only be made as 3 layers, rather than 4?
So with BluRay you get 2 layers for the DVD (allowing a DVD 9 - as now - to
be provided) as well as a single layer 25Gb BluRay (which is only 5Gb
smaller than a dual layer HD-DVD) which can comfortably carry an HD movie.

However with HD-DVD you can't carry an HD movie on a 15Gb single layer, so
you have to use two layers of HD-DVD (allowing 30Gb) leaving only a single
layer for DVD, allowing only a DVD-5 to be provided for.

Of course there is no guarantee that dual-standard releases will be that
significant - but it looks like BluRay has the edge there? (Though of course
HD-DVD releases with poor quality DVD transfers may serve to increase the
difference between the qualities of the two systems)
