The vast majority of manufacturers are behind BluRay--Matsushita (Panasonic), Sony, Phillips, Pioneer, Dell, HP, etc.
HD-DVD has NEC (what have they done lately in the consumer sector?), Toshiba (makers of the world's worst DVD players), and I believe Samsung (makers of the world's second worst DVD players).
Think Toshiba, NEC, and Samsung can keep up with hardware demand? No way.
The victor will most likely be decided by the enthusiasts who purchase the first decks. The vast majority of people I've spoken with are firmly behind BluRay or plan on purchasing both.
It's the killer film arsenal brought to the table by the studios that will ultimately decide the outcome though. Both sides have strong content.
