It has to do with the fact the bluray costs so damn much while providing marginal benefits.

If it has marginal benefits, why, when I have to choose between the DVD edition or the bluray edition, do I always pick the bluray one? Once you tried it, it's hard to get back to the DVD.

Walt Disney Co., the second-largest U.S. media company, desperately hopes sales of high-definition Blu-ray discs in the U.S. will overtake DVDs within two years,  to offset the fact that Disney has an already highly saturated market.

Consumers will adopt the new technology "much sooner than we think," David Jessen, Disney vice-president of Blu-ray and DVD creative production, said in an interview, "or I will be on my way out the door."  "I keep telling the CEO and the board that it's right on the verge of becoming really big in the U.S., where in two years Blu-ray will eclipse DVDs."

In February, the Blu-ray disc technology won against Toshiba Corp.'s HD DVD, setting the new high-definition standard in the entertainment industry's largest format war since VHS beat Betamax in the 1980s. Blu-ray discs can store 50 gigabytes of data, about six times more than conventional DVDs.  They also have many other technical advantages that the average consumer is clueless about, but which will lead them--sheeplike--into spending amazing sums on movies that look better than their already great looking DVD versions.

Disney is releasing classic movies including Sleeping Beauty this month in the Blu-ray format to encourage consumers to start using the new technology, so that they can once again sell their classics to the 99.99% of consumers who already own them on DVD or VHS.

The film is the first release to include the BD-Live network system, enabling viewers in different locations to chat and create communities while watching the same movie, Disney said.  "Almost a dozen people are expected to take advantage of this opportunity to completely distract them from the movie's experience."

Shopping for HD-TVs and Blu-ray players will help the technology "take off big" after the holiday season, Jessen said.  "No, bigger than big.  I mean hugely big.  Perhaps even ginormous." "Prices of HD-TVs and Blu-ray players are coming down everywhere, and should quickly replace all the bedroom TVs, the in-car players, computer drives, and portable players." Blu-ray discs "will also drop as mass adoption takes over and people stampede into stores waving their wallets and screaming about how the current economy has given them more money than they know what to do with."

Then Mr. Jessen broke down and openly sobbed, ending the interview.

So there is another opinion, this time from someone in the industry.
