I would offer a different opinion. For about 18 months following the BetaMax demise, I saw little to no sales on VHS tapes, and about an 18% price increase where I was at.
Not sure how lack of competition promotes pricing incentives to the consumer.
There is still competition. Samsung, Sony, Panasonic, Sharp, and a bunch of others may BD players. The mass adoption of one format will encourage people to buy these players and will reduce the price. That's how EVERY electronic device I've ever owned worked. My first DVD player was $600+ if I recall. First plasma's were $10K+, etc etc. Prices will come down because of mass production/adoption.
