The movies they have made right now are all MPEG2.
Sony is very unlikely to want to break compatibility with new encodeing on
new movies.
MPEG2 which is litterally half as effective as MPEG4 for comprable quality.
Single 27G BluRay discs not only cost more to make than a dual layer HD-DVD
(30G) but they perform like a 13G HD-DVD would on prerecorded titles.
