Forgive me if I am wrong but as long as Sony don't get involved in setting the standard I don't see how it matters whether the studios like it or not. How can they dictate how you connect your components together when they won't know ? Are they going to stop selling DVDs/BD disks to anybody who cannot sign a document saying that they have HDCP compliancy ? Which would be good because I think that if anything would make a change happen quick this would.
In fact about the only way to make the new standard have HDCP is for the (whoever licenses that stuff) to refuse further licenses to any company that is dabbling in new technology ie blackmail.
HDCP has interfered so much in allowing me to set up my audio/video the way I want, and cost me a lot extra, that anything that would allow me to dump it I would be interested in. Anybody who wants to pirate does it in spite of HDCP. In fact, although I don't bother, if I ever did decide to make backup copies of my DVDs/BDs it would only be to get rid of the stupid Anti-Pirate message beginning on most disks. If you add up all the time people spend wasting time having to watch it you could add 1% to the GDP.
China doesn't seem to have this problem and look at their economy.
