In response to all those saying "Bluray is Dead":
Do you think the industry will let this happen? For a new format to take over, it has to have the support of the movie industry and the hardware manufacturers. When they both finally committed to BR, they will have based their decisions on a predicted life of BR as a viable product - DVD probably had 10 years before BR take-up started to match what DVD sales had been 10 years earlier.
Just because an improved technology comes along, the industry isn't going to drop BR and adopt it for 2 reasons: 1) Amortising its existing commitment to BR and 2) If it drops BR now, no consumer is going to commit to a new format for fear of the industry dropping it within 12 months when another technology comes along, like it would have done with BR.
So, market forces stifle technological advance, but at least it gives us the benefits of consistent, established technology and competition.
All IMHO, of course.
