Personally, I never believed that Blu-Ray would make it as a mainstream format anyway. Sony hasn't learned with Beta-Max and more recently with UMD, making your own propriatary media format just doesn't work. One of Sony's biggest folly's was basing their next-gen gaming system on a very expensive, unproven medium format. Everything that I've heard going wrong with the PS3 can be attributed to the inclusion of the Blu-Ray drive: From the shortages at lunch due to a shortage of blu-laser diodes, to really slow load times from the slow speed of the drive, now to rediculously easy piracy.
Sony was the market leader, and held it for a long time, but they may have slipped up one too many times this time. Nintendo used to be the market leader at one time, but again a few too many slip ups. Nintendo actually did the opposite of Sony, keeping an outdated medium for far too long. In something like the gaming industry you could really screw up if you adopt too quickly, or not quick enough. That's why I really appreciated it when I heard about the 360's HD-DVD add on. I have to give it too Microsoft there, instead of forcing their customers to adopt a new and unproven technology, they simply gave early adopters an option to upgrade, while still using the proven DVD format, with the possibility of upgrading the drive if HD-DVD does become dominant in the 360's life span.
That was the other problem from Sony: You can't force consumers to adopt a format that they really don't need right now. I can still find some new movies on VHS at Wal-Mart, even though DVD players are $20. It takes people a very long time to adopt to a new format, and if Sony is forcing their customers to buy it, and now have all these problems with it, then yes, it has the potential to kill Blu-Ray as a medium before it even gets started.
I don't know, guess I went off on kind a rant there, lol, sorry about that. I'm really not anti-Sony, I think that they're a great company, they've just screwed up too many times with the PS3.
