that guy didn't know what he's talking about the first time, he still doesn't.
blu-ray sales are low because people are spending less in general. and their shifting more of their money towards saving/investing. movies are considered minor luxuries to the majority of people. most are content to go to the theater a couple times a month & just watch TV. the only titles which have done really well are blockbusters which people enjoy re-watching & showing friends.
when the economy gets more stable and the MSRP drops below $20 (w/ $12-15 being typical price) it will pick up. a $150 player doesn't mean much if the movies for it are $30-40.
So only the people who buy blu-ray are shifting away from buying movies?
Entertainment rarely suffers with recession people will cut back on other things first.
