Sony predicted $1 billion in Blu-Ray software sales for 2008, that $760 million figure has to be a pretty big disappointment despite surpassing the conservative 10 million player estimates.
Means the PS3s that were sold aren't being used as much movie watching, in concert with the economy, the cost of the movies and relatively lackluster PS3-as-trojan-horse sales.
As I said in another thread, tentpole releases are going to be used to portray an overall health of the format when it's not as rosy as it could/should be, but the backers are still in profit-taking mode with these MSRPs so high. It's improving, but has a long ways to go. The Dark Knight is probably 10% of their sales for the year. 1 title. The only figure I could find for it's 2008 sales was from the week after it's release, it was already at 1.7m units sold... almost 7% of the annual BD sales. (though, some reports showing 1.7m as of 12/17.... others from after the new year reported by the BVA have it listed at 1.5m sold in December?)
