it will take some time before blu-ray disc replace DVD\'s - only 28 percent of Americans own an HDTV (which is impressive, but a minority none the less).
When it does, it will be a mere bridge to digital distribution.
However, I own a PS3, and I like watching things in high-def, so it is my format of choice at the moment. I don\'t see any other threats coming in the near future, and don\'t give me any holographic disc crap.
