Sony is going to fight tooth and nail for this one. It's the first time that one of their proprietary formats became an industry standard. They rest are failures (ATRAC,BetaMax,MemoryStick,MiniDisc,etc). They still won't cater to independents though.
Sony invented the 3.5-inch floppy disk, and the audio compact disc was invented together by Philips and Sony. Were these somehow not proprietary?
a) proprietary formats hurt independents
b) this is yet another anti-piracy heal of crap which will hurt consumers.
So yea I would not be concerned with blue ray. If the porn industry does not embrace it it won't be the next big thing.
However being that this is sony you are garanteed that they will cater to destroying independents and growing sony's monopoly.
